On my Newtonian: If I'm using a MPCC w/this zoom and alternating between visual and T2 w/Nikon APS-C, is there some sort of extension I could use (clicklock preferred), so that I don't have to add/remove the focuser ring extension each time? To make matters even more fun, this will be used on a Bresser Hexafoc... Is this doable?

How waterproof or weatherproof is this zoom eyepiece please?

Question by: Adrian on Jan 20, 2022 7:42:00 AM | 1 Answer(s)

Rating of Question

Making a zoom become waterprove has severe consequences. The designer must decide if he can accept a hard rotation action or not. For use with a spotting scope it "could" have been be made waterproof by fitting O-rings into the rotating mechanics to seal the moving area. However - this does work on a short and relatively lightweight spotter - but the rotation movement of the zoom-action in this case is getting stiff and hard to rotate.

For an astronomical telescope this would be an impossible behaviour because the telescope would wiggle when the zoom-action is so hard to turn - especially in winter.... Also the "Click-function" would become impossible to feel - the whole eyepiece would become "just another zoom".

So - in order to enable an effortless zoom action with the click-stops to be just sightly noticeable (if these are "hard-clicks" likewise astronomers do complain!), we omitted a tight seal in the area relevant for the zoom action. However - as soon as the eyepiece is connected onto a telescope (or spotter), the upper lens parts certainly are O-ring sealed and the eyepiece can justifiedly be called water resistant, because rain will not enter.

At any rate - if you are in need of a completely watertight solution for harsh outdoor use on a spotting scope, this eyepiece may not be a solution for you.

With eyepiece projection, the image at the edge is extremely blurred. What could be the reason for this?

Question by: Anonymous on Sep 2, 2019 11:46:00 AM | 1 Answer(s)

Rating of Question

For eyepiece projection with our Morpheus and Hyperion (zoom) eyepieces, we recommend a distance between eyepiece and T-ring of 40 mm on full-frame cameras, in addition to the 55 mm that were the flange focal distance of all "SLR" and DSLR camera bodies for decades when a T-ring was placed in front. Only with a T-ring that maintains this distance can old lenses with a T-thread deliver sharp images. Therefore, it has been tried to take this distance into account in all designs, because this is the only way to ensure that the sharpness performance is optimal. Of course, all this is only valid to a limited extent today - because the DSLR standard is losing it importance and the term „T-ring“ is all too often reduced to the mechanical thread and not the correct distances. In our brochure on digiscopy, we have therefore stated the back focal distance of 55mm. With a DSLR (full frame or APS-C), this distance is also maintained in good approximation with modern, narrow T-rings, which are intended for use on telescopes, where every millimetre often has to be haggled. For Micro Fourthirds cameras, for example, we have a special adapter that allows both an adaptation with the 55mm standard support dimension and a much shorter adaptation.

Mirrorless system cameras have a much shorter back focal distance than comparatively large SLR cameras. The available T-adapters are usually for use with telescopes with a moving focuser. Here the shorter back focal distance must be compensated by additional extension sleeves, if a certain distance has to be kept.

The example adaptations in our digiscoping brochure thus apply to all T-adapters that follow the T2 standard and deliver a back focal distance of 55mm.
The indicated distances of
min. 40mm spacer sleeve plus 55mm T-2 flange focal distance for full format
min. 30mm spacer sleeve plus 55mm T-2 flange focal distance for APS-C
min. 15mm spacer sleeve plus 55mm T-2 flange focal distance for MFT
were empirically determined (Canon full format, Nikon APS-C (slightly larger sensor than Canon APS-C), Panasonic MFT) and are the values at which the image looked good, i.e. no (disturbing) distortion could be detected in nature photography. However, only the Hyperion Zoom without Barlow lens was used. For decades, we had in principle recommended the 40mm extension; with the smaller sensors, shorter distances (and less magnification) are also possible. The overall length of an adapter ring from the M43 eyepiece thread to T-2 was neglected, or it was regarded as part of the eyepiece.

With shorter overall distances than indicated above, the sharpness in the edges is catastrophic. Only with these distances the image is enlarged in such a way that the entire sensor can be used.

When working with an additional Barlow lens for even more magnification, the resulting effective focal length increases extremely and the system becomes more difficult to control. The thick stack of lenses does not make the image any better, and the telescope opening must provide sufficient resolution, also in relation to the pixel size of the camera. For highest magnifications we therefore recommend the FFC instead of the eyepiece projection in combination with a barlow lens – more on this below.

What can easily be overlooked is that, depending on the camera type and the telescope aperture ratio, a more or less pronounced vignetting is unavoidable.

We regret that we can’t give a binding (or universal) recommendation for an eyepiece-Barlow-lens-combination - for no single eyepiece on the market - where vignetting does not occur. Eyepiece projection is basically a compromise and has been "invented" for planetary photography since the beginning of all photography in order to be able to image a small object in the center of the image with excellent sharpness and very long focal length. The further development of the eyepiece also made it possible to enlarge the usable image area - however, this method is still a compromise. We therefore do not claim that you can achieve perfect sharpness over the entire image field with an eyepiece and a Barlow lens. We also do not claim that you can achieve a completely unvignetted image field!

For exactly this reason - because there has been no solution from anyone in the world (and still is not) - we asked Carl Zeiss-Jena in 1990 to calculate for us a plano barlow lens of any complexity for medium format cameras. Ultimately, this was only possible with two additional crystal substrates made of genuine calcium fluorite (not comparable to simple ED glass). For the Baader Fluorite Flatfield Converter (FFC) Barlow - which can produce an image circle of 90 mm from 4x to 8x - an aperture ratio of 1:10 - as is the case with many refractors - was the basis for calculation at that time. The 90 mm image circle was due to the fact that the famous "PENTAX 6x7" medium format camera was available at the time - with a 90 mm image diagonal.

To this day, this FFC converter lens system is "the sharpest of all Barlow lenses" in the world. And since the full 42mm format uses less than half of the FFC’s 90mm image circle, the FFC works so well even at an aperture ratio of f/5 that it delivers diffraction-limited sharpness even with CMOS chips with ~ 4my pixel size (if the telescope optics and seeing are good enough). However, this only works so well due to the large image distance. If you are looking at the "Baader FFC-Barlow", you will see that the image distance has to be varied between 80 and 150 mm (or even more). So you pay for the excellent optical performance with a very long mechanical construction. Without an excellently stable focuser, this can only cause frustration. Anyhow - You will surely find enough judgments which testify that there is no other projection lens system with sharper - and not vignetting - imaging.

So if photography with very long focal lengths is your main focus, then you would have to replace the combination of the eyepiece with a 2.25x Barlow for a FFC - in addition to the armada of extension rings, which are necessary if you want to use this projection method without mechanical distortion.

Can you recommend a reducer to use with Mk IV zoom? I want to reduce the magnification min/max range ... THX

Question by: Michael on Jan 26, 2017 3:39:00 PM | 1 Answer(s)

Rating of Question

You can increase the max. magnification with the Hyperion Barlow. The combination of Mark IV and Barlow results in focal lenghts from 3,6 - 10,7
To reduce the focal length of your telescope however, in order to increase the field of view (= less magnification) is more difficult. A reducer has to be calculated to optically match your telescope brand and model, otherwise you may not be able to reach focus and the image quality might be horrible, with an enormous amount of field curvature and/or spherical aberration

Unfortunately reducers are not our speciality, since we only offer reducers for very few such special optics. Also please note that the reducers that we do offer (such as the Alan Gee Telecompressor #2454400 - calculated for C8 or higher Schmidt-Cassegrains) are all mainly optimized for photography and cannot be used in combination with prism or mirror diagonals since the optical backfockus just is not enough.

Sorry, this is quite a complex area. For this reason we never offered a "universal" reducer for lowering magnification during visual observation.

I want to do projection photography with the Zoom Mark IV using a Canon EOS R with and without the Hyperion-Barlow 2.25x using the 2" barrel with my telescope.

I believe I can do this by using a Wide-T-Ring Canon R (2408336), a UFC S52 Camera-Adapter (2459119), a UFC Base (2459110), a UFC S70 / T-2 Adapter (2459130), a Baader TQC/TCR Heavy duty T-2 Quick Changing System (2459130) and a M43 / T-2 Adapter (2958080).

What I am not sure of is exactly what UFC S70 and/or T-2 extensions I would need to get the recommended back focus for use with the full frame EOS R camera. I am also not sure if I could fit the #2459130 in the setup, it would be convenient but by no means necessary. I am also not sure if I would require different extensions when using the Barlow.

Can you please confirm if these parts will work as I intend (with or without the #2459130), what extensions I should use to get the recommended back focus with the EOS R camera and if I need different extensions when using the Barlow?

Rating of Question

The top lens doublet as well as the zoom ring on the Mark IV and previous Hyperion Zoom models are indeed O-ring sealed, to permanently shield off water (and dust) entry when the Hyperion Zoom is exposed to sudden rainfall. while inserted into a spotter for instance.

What is not sealed in the same way is the front lens element inside the 1 1/4" nose piece during its travel up and own. We sacrificed that O-ring seal in all zoom models in order to make the Click-mechanism work effortless and to avoid that "hard feeling" of most other zooms when changing magnification. This is certainly a concession to its primary use on astronomical telescopes. Here the zoom ring must work without "resistance". On most other zooms the telescope will come off target or start to "wiggle" everytime when rotating the zoom ring actually is a real effort.

Effortless handling - is what we try to achieve with this zoom - as well as intuitive indication of the distinct magnification stops. This smoothness in operation is just one of the reasons that made this Zoom such a success among Astro-Amateurs - without most people noticing even why they have that positive feeling, compared to using other zoom eps.

Also when using the Mark IV on your spotter you will find it a side-benefit, to reach high magnification without loosing target - just because the zoom were so darn stiff to rotate.

For your application attached to spotting scopes, what remains is that you won´t have any water entry while the Hyperion Zoom is mounted onto the spotting scope. The bottom design of the zoom creates an overlapping shield, to not have water creeping into the 1 1/4" receptor.

Rating of Question

It should be no problem to use the eyepiece on any telescope. We have designed it so that it also works with spotting scopes which have a short back focus, if you use the spotting scope adapter (A) instead of the telescope adapter (B). This means that the eyepiece needs to be some mm closer to the telescope than most 1.25" eyepieces, if you use the spotting scope adapter.

But f you can use standard 1.25" eyepieces, you can use the Zoom, too, especially with the telescope adapter (B). Most 1.25"pieces have got the field stop more or less at the connection between the 1.25" nosepiece and the wider body holding the lenses.

If you need to place the eyepiece farther away from the telescope, please check the following things:
- First of all: Can you reach focus with other eyepieces?
- Are you using the telescope adapter (B)?
- Can you use a 2"/1.25" reducing adapter instead of the 2" nosepiece? This gives you sometimes more than a centimeter

With a Newtonian, there are two more things to check:
- Is there an extension tube for visual use included? Many Newtonians have got an extension tube at the focuser. This has to be removed for photography with a DSLR (which needs to be 55mm closer to the image plane of the telescope than an eyepiece).
- Was the main mirror moved upwards in the telescope tube (by purpose or during collimation)? This is done sometimes to achieve focus with a DSLR and may result in the impossibility to achieve focus with an eyepiece.

You need
Hyperion / Morpheus® T-Adapter M43i/T-2a (M42x0.75) # 2958080
Baader Wide-T-Ring Sony E/NEX Bayonet with D52i/M48 to T-2 und S52 # 2408317
and several T-2-extensions to achieve the necessary distance between camera sensor and bac of the eyepiece, depending on sensor size and desired magnification.

For an APS-C-camera like the A5000, the distance should be at least 85mm, where a regular DSLR with T-ring is 55mm deep (that's the flange focal distance or backfocus of camera plus standard T-ring) - so you'ld need a 30mm extension.
The Sony E-bayonet with our Wide T-ring has got a flange focal distance of 26mm, so you should use about 60mm extensions, e.g. by combining
Baader T-2 / 40 mm Extension Tube (T-2 part #25B) # 1508153
Baader T-2 / 15 mm Extension Tube (T-2 part #25A) # 1508154
Baader T-2 / 7.5 mm Extension Tube (T-2 part #25C) # 1508155
A larger distance will give you a higher magnification; a shorter distance will decrease the useable image circle, so that there may be distortions in the edges.
For the resulting effective focal lengths, please see the digiscoping PDF linked above

Thank you kindly for your interest in this amazing optical design of the Mark IV Hyperion Zoom 8-24. In fact - few optical designs may have been so "long-lasting" as this one.

Design changes were always done to improve on the eyepiece mechanics - and the present Mark IV-mechanics, small form factor, low weight and excellent adaptability really will be very hard to improve. Only we should do more adapters, to fit this eyepiece onto more other brands of terrestrial spotting scopes - alas, engineering time always is too short.

The "optical success" though was caused by the extremely "good-mooded" viewing behaviour - and the fact that the optical image quality is "getting better" with increased magnification, This is in sharp contrast to most other Zoom-designs, were the smallest magnification forms the base of design and the higher you magnify the more optical imperfections become obvious. And the core reason for this "inverted optical performance" of the Hyperion Zoom of course is : Carl Zeiss.

When in 1995 Carl Zeiss Jena decided (unfortunately) to abandon astronomical telescopes from their product portfolio, by contract they had chosen Baader Planetarium for continuing their product service work. This did include the drawings of existing products for fulfilling all service obligations, including their "Vario (=-Zoom)-eyepiece" of spectacular design - at a production cost that was meant to revolutionize the market. This design formed the base of the first Hyperion-Zoom and it still is the same today - except for improvements in the coating technology during the last quarter century.

Changing this optical design will inevitably result in deterioration of other parameters - there is only so much degree of freedom in a good design. Changing anything does cause the eyepiece to change as a whole For instance it would become considerably longer with more lens groups or at minimum larger lens distances As you say it will destroy one of the other parameters you like, form factor and weight.

The low magnifications definitely do not benefit as much if one tries to - say - keep the apparent field more similar to the 68 degree at highest magnification. Just like you, tenths of thousand of amateurs do like how this eyepiece performs overall - and they do like the amazingly low price at which this performance is being offered.

So please bear with us if we still did not find a way to improve the optical performance without deteriorating any other parameter - including the affordable price.

1) I was told that the 1.25 nose piece does come off but when I looked at one in the store it looks like there are small set screws in the side. I tried to twist off the 1.25 and it would not budget. Does it come off?
2) the vendor said the 2" is only for ease of use. You get no advantage of using the 2" re more light gathering. Is this true?
3) If #2 is true then you do not buy 2" filters with this eye piece
4) you do not get the normal "space walk" feel of the 2" with this eye piece if #1 is true so you might as well buy a 1.25 zoom or a 2" dedicated zoom if you want that 2" feel?

1) The 2" nosepiece can be removed, so that you can access the 1.25" nosepiece, which has also the safety kerfs. You can remove it, too, to switch between the adapter rings for spotting scopes and telescopes as described on page 5 of the manual at https://www.baader-planetarium.com/en/downloads/dl/file/id/356/product/3117/description_and_recommended_accessories_for_the_hyperion_universal_zoom_mark_iv.pdf
If you remove the 1.25" nosepiece, you'll see a smooth hull with a diagonal slit - this is a part of the zoom mechanism. The lenses inside can not be removed without destroying the eyepiece, only the smooth hull can be removed to attach the eyepiece to some spotting scopes.

2 & 4) This is true. 2" nosepieces are only interesting for eyepieces with longer focal lengths than ca. 32mm - the true fields of view (the part of the sky which you can overlook) of eyepieces with smaller focal lengths always fit into 1.25" nose-pieces. There is no advantage in using 2"-lenses at 24mm, even less at 8mm.

Please note that the space walk feeling is only an effect of the apparent field of view of an eyepiece. To achieve it, you need an apparent field of view of about 76° like with our Morpheus, where you can still see the edge of the field of view, but it starts to dissappear when you observe for some time. The Hyperion Zoom has got a smaller apparent field of view, so you'll still notice the edge. But please compare its field of view to that of other zoom eyepieces! Especially note that the apparent field of view increases with higher magnification, while many other eyepieces show a smaller field of view at high magnification.

Basically, it is a 1.25" zoom with an included 2" adapter, because a 2" eyepiece in this focal range wouldn't make any sense. But the 2" housing provides more stability, especialy if you attach a camera to the eyepiece. I don't know of any 2" eyepieces at all.

3) We'd recommend always 2"-filters, because you use them also with 2"-pieces for lower magnifications, or mount them inside of a 2"/1.25"-reducer, so that you can change 1.25"-eyepieces without changing the filter. But if you look only at this eyepiece, yes, there is no difference if you use 1.25" or 2" filters.

We could not test it with every spotting scope on the market, but if you use the included spotting scope ring and the included 1,25" barrel, there should be no problem - the Pentax is designed for the 1.25"-standard, and the Hyperion Zoom works with all similar spotting scopes which we have tested. If the Pentax 65 works with any 1,25" eyepiece, then the Hyperion should work fine, too.

I have the Pentax 65mm spotter scope and this zoom does not reach infinity focus at all zoom ranges. Needs a bit more in focus than my other eyepieces which do come to focus in the same scope. The Pentax uses standard 1 1/4" eyepieces. It s just barely missing focus...maybe another 1/8" would work over all the zoom range. Too bad as other than that this is a great eyepiece with all my astronomy telescopes.

I recently purchased both the Hyperion Mark IV zoom and Hyperion 2.25 barlow and have a question regarding set-up.

While the box for the zoom suggests that the barlow is attached directly to the eyepiece (see caption "thread for Hyperion Barlow" and arrow pointing directly at the eyepiece), the manual (https://www.baader-planetarium.com/en/downloads/dl/file/id/356/product/3117/description_and_recommended_accessories_for_the_hyperion_universal_zoom_mark_iv.pdf) indicates at p. 11 that "the barlow is attached onto the 1¼" nosepiece" (i.e. nosepiece between eyepiece and barlow).

Could you please advise as to the correct set-up? Does it matter one way or the other (my preference would be not using the eyepiece but I am happy to do so if this will improve performance)?

Many thanks in advance for responding at your very earliest convenience. Your kind assistance is much appreciated.

We have a description of the various camera adaptations in the PDF "Digiscoping - camera adaptations for afocal photography and eyepiece projection" which you can find in the download section of the product website or here:
https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/3117/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf
For a full-frame DSLR, you need
1x Hyperion / Morpheus® T-Adapter M43i/T-2a (M42x0.75) # 2958080
1x Baader T-2 / 40 mm Extension Tube (T-2 part #25B) # 1508153
1x Baader Wide-T-Ring Canon EOS with D52i to T-2 and S52 # 2408332

For an APS-C, you only need a 30mm extension. So, you can replace the 40mm extension either with two Baader T-2 / 15 mm Extension Tubes (T-2 part #25A) # 1508154, or with one Baader T-2 / 15 mm Extension Tube (T-2 part #25A) # 1508154 and one T-2 Quick Changer (either Baader TQC/TCR Heavy duty T-2 Quick Changing System (T-2 part #06A & #07) # 2456322 or Baader Complete T-2 Changer System (T-2 parts #06 & #07)

Description

Details

Continous magnification with ClickStop at 8/12/16/20/24 mm

The Hyperion Universal Zoom Eyepiece can be adjusted steplessly from 8 to 24 mm of focal length. In addition focal lengths 8 / 12 / 16 / 20 / 24 mm are marked with „ClickStops“, so that any of these five magnifications can be set intuitively. This is especially of importance for use with binoviewers.

Two Mark IV eyepieces can be set most easily to the same magnification, even in the dark. The click-sound has been smoothened, so that hunters or birders will not disturb their targets when zooming in on them.

Hyperion Mark IV Universal Zoom 8-24mm Eyepiece

with 1¼" / 2" nosepieces and ClickStop-Action

Zoom-lenses in general are not really famous for high quality optics. Also many zoom-eyepieces do not deliver the best possible image quality at high magnification because they were designed with focus on the price-tag so that image sharpness and field size is getting worse with increased magnification.

The recognition that the Hyperion Zoom Eyepiece enjoys is based on the fact that it was designed the other way around: the glass selection and most of all the principal optical design and consequently the lens polish quality – all were optimized for the highest magnification. And obviously, when closing in on an object you will want the field of view to increase and not to have it become seemingly smaller. Hence the Hyperion-Zoom shows the largest apparent field of view at highest magnification.

For many birders, observers of nature and astronomers alike, the Hyperion Zoom Eyepiece is their favorite eyepiece, it is also the only zoom-eyepiece that was designed from ground up to be used with bino-viewers.

Either 1¼" or 2" can be adapter (not simultaniously) to the Hyperion Universal Zoom Mark IV

What's new in the model "Universal Zoom Mark IV"?

Even Bestsellers can be improved: The fourth generation of this eyepiece weighs 290 gram and is lighter by 80 grams than its predecessor - it now has 55 mm diameter to become useful in dual mode from 55 mm interpupillary distance, both features make it especially desirable for use with bino-viewers. The adjustable eyecup can be removed to expose the M43 video/photo thread and create the maximum "nose space" for using it on binocular viewers with the supplied winged rubber eyecups - for maximum concentration on the target. The click-stop action has been smoothed out to more easily access the magnification stops at 8/12/16/20 and 24mm (click-stops are mandatory to easily and precisely set both eyepieces to the same focal length for effortless binocular observation without eye-strain). The zooming-mechanism as well as the inner zooming rails for all lens groups have been modified to improve cold temperature operation and the parfocalty for each focal length has been finetuned.

Most important however – the Mark IV offers almost 4 mm more backfocus. This is most beneficial for application with a multitude of spotting scopes. Two different Adapters for telescope and spotting scope adaptation are included with the eyepiece (Spotting-Scope Adapter „A“ and Telescope-Adapter „B“). Read more at "Telescope-sided Connections").

The Mark IV comes with both the 2" and 1¼" nosepieces mounted, each nosepiece having it´s own dust cap and both nosepieces are threaded to accept either 1¼" or 2" eyepiece filters. Both nosepieces are free of the hated undercuts. Instead our proprietary Zero-Tilt Safety-Kerfs provide an added measure of security by reducing the tendency of an eyepiece to slip from an unlocked eyepiece clamp. An additional little feature is the Baader-yellow soft pouch with integrated belt strap – which fastens onto many tripod legs just as well, to serve as a bin for all dustcaps that may go astray otherwise.

As usual with Baader eyepieces, the Mark IV offers an M43 photo/video thread on top of the eyepiece, to allow attachment of any desired DSLR or T-2 accessory for mounting a video-camera by means of the optional M43/T-2 adapter ring #2958080. Unchanged is the optical quality, 68° field of view at highest magnification, Phantom Group multicoatings, a large adjustable eyecup or alternatively two M43 rubber eyecups for bino viewing. An optional spacer ring M43/M43 (#2954250) with 7,5 mm extension enables the user to increase the height of these eyecups in case of need.

The Mark IV likewise accepts adaptation of the 2.25x Hyperion-Barlow onto the 1¼" nosepiece, to transform into a high power zoom, featuring the magnification range of 3.6 to 10.7 mm. The Hyperion Universal Zoom Mark IV is available individually (#2454826) or as set together with the 2.25x Hyperion Barlow (#2454827)

Please also note our detailed Hyperion Universal Zoom Mark IV Instruction manual (also under the tab "Downloads") for further information.

Connection Options and Included Items

Telescope-sided Connections

The Hyperion zoom Mark III comes with two removable barrels (1¼ "and 2"), as well as an 2" SC-thread for direct connection on telescopes or mirrors/prisms with the optional 2"/2" changer ring (#1508080).

Furthermore included in the scope of supply are two adapters of different height - both with 1 3/8" inner threads - for following uses:

Spotting Scope-Adapter A: 4mm gain on backfocus. the Mark IV focuses with all tested spotting scopes (optional adapters available for most major brands)
Many spotting scopes nowadays do allow the mechanical insertion of astronomical 1¼" eyepieces – but in many cases this combo cannot focus to infinity. By utilizing the supplied spotting-scope adapter ring "A", the Hyperion Universal Zoom reaches almost four mm deeper into the eyepiece clamp of all those spotters, to safely reach infinity focus. When removing the 1¼" nosepiece, a 1 3/8" thread inside the "A"-ring will make the Mark IV firmly thread onto all Celestron-Ultima spotters and it´s namesakes. Optional available is a bayonet-adapter for Zeiss Diascope-spotters (#2454500). Threaded adapters for many other famous spotting scope brands (that still don´t allow 1¼" eyepiece adaptation) will become available in the future – now that it makes sense to produce them
Telescope-Adapter B: Sufficient distance to clamping screws..
When using the Mark IV on a telescope though, the "B"-ring (supplied) should be chosen instead, to keep the bottom of the eyepiece flush with the upper end of most star diagonals. Otherwise the bottom 2" SC-threaded holding ring that holds the "A" or "B" ring in place may directly rest on the clamping screws of the star diagonal. The supplied 2" SC-ring also allows the Mark IV to firmly mount the eyepiece onto any SC-thread, especially onto our 2" clicklock star diagonal, with the help of the 2"/2" adapter (#1508020).

Please see the instruction manual for more information on changing both Adapters.

Camera-sided M43 thread

Camera-sided Connections

As usual with Baader eyepieces, the Mark IV offers an M43 photo/video thread on top of the eyepiece to directly attach most video cameras. It also allows attachment of any desired DSLR or T-2 accessory by means of the optional Baader Hyperion T-Adapter M43i / T-2a #2958080. An optional spacer ring M43/M43 (#2954250) with 7,5 mm extension enables the user to increase the height of the included eyecups in case of need or to attach M43 cameras without touching the lenses.

A further connection capability offers the SP54-system thread-in the form of the Hyperion DT ring system. For this system, the transition ring M43/SP54 #2958086 is suitable for the Mark IV zoom eyepiece. This adapter enables the connection of all common camera lenses on the Hyperion zoom to use it for Eyepiece Projection. Those connection rings are called "Hyperion DT rings", see our section "Eyepiece accessories" .

Read more on camera connections, required distances and adapters in our detailed instruction manual

Hyperion Zoom included eyecups

Included eyecups

Three different eye cups are included in the basic equipment of the eyepiece.

Initially mounted is the large height-adjustable eyecup that also fastens onto the M43 photo-thread of the eyepiece. By rotating it counterclockwise the height will increase. This eyecup easily unthreads simply by rotating it upward further than the uppermost stop - this reveals the M43-thread connection
A none-folding rubber eyecup alternatively fits straight onto the M43-thread. This is the preferred solution for observers without glasses at a binoviewer. It gives you enough room for your nose and good support to keep the perfect eye distance.
An even lower eyecup with foldable winged eye shield especially serves for wearers of eye glasses, the flappable side shields block stray light and side image information not part of the eyepiece field of view. This helps to concentrate on the target when using a binoviewer.

The camera at the eyepiece

Pitfalls and opportunities In this article we want to show the different ways to enlarge the image or to take pictures through the eyepiece quickly and easily with a camera. These techniques are interesting for photographing the moon and planets as well as for anyone who wants to photograph through an eyepiece - for example, for nature photography through a spotting scope. "Getting closer" is the goal of many photographers. In other words, the longest possible focal length to image the objects as large as possible on the sensor. A practical rule of thumb for astronomers is that the sun and moon appear on the sensor approximately with a diameter of just under one centimeter per meter of focal length. Since long focal length telescopes quickly become very unwieldy or at least require a very heavy mount, it is difficult - especially as an amateur - to reach for the largest possible telescope. A 14" Schmidt-Cassegrain with 3900 mm focal length, as it can be found on many observatories, is for most people the longest focal length telescope, which they can access at least through a club membership. So how do you get closer? The answer is simple: a magnifying...

Barlow lenses, their magnification factors and working distances

Again and again the question arises whether a barlow provides the correct magnification at all. It is often overlooked that the magnification factor always depends on the correct working distance - you can read more about this in this PDF using the VIP Barlow as an example: Different Magnifications with the VIP-Barlow # 2406101 To settle this question once and for all, we took a few comparative shots on an ED80/600 telescope with a monochrome camera. Due to the seeing on a hot summer at an outside temperature of 30 °C, the shots of a neighbouring roof were somewhat unsteady, so that the sharpness of the individual frames is only of limited use for judging the quality of the Barlow lenses, but here we are only concerned with the scale of the image. On this occasion, the focus shift was also measured: A barlow moves the focus point and is often used to come into focus when there is not enough back focus. To do this, the actual barlow lens element is placed deeper in the focuser and the focus moves outwards. The reference shot: Fokal, without an additional barlow lens At first, a shot without an additional barlow...
