Baader-FlipMirror II Star Diagonal (BFM II) with three ports:
- Straight-through (S52, M48 and T-2 on both sides) for full-frame camera, spectrograph, or other instruments
- Adjustable T-2 thread on top for eyepiece clamps, video modules (up to 32 mm image circle) or even a binoviewer
- Bottom flange for the optional Off Axis Guider for Baader FlipMirror II (BFM-OAG) (#2956951 , € 122) or for an optional calibration lamp for quick calibration of spectra without removing the spectrograph
Precise surface-mirrored flip mirror with multi-layer Al coating, for high-resolution images with cameras with small pixels
The back of the flip mirror is also Al coated and masked to direct the light of an optional calibration lamp onto the slit of a spectrograph
Enables precise adjustment of all light paths
Shortest possible overall length for any application – compatible with a large number of adapters from the Baader Astro T-2 system, the M48 system and the UFC system (Universal Filter Changer)
Rotatable M48 connection rings made of hardened, stainless steel on front and rear, backlash-free adapted to the BFM housing. Can be fixed in the optimum position to rotate any accessory around the optical axis.
Prepared for an optional toothed belt for motorization (e.g. by Steeldrive II motor focuser with Controller (#2957165 , € 665) ) – basic requirement for image acquisition, guiding and spectroscopy in remote observatories

I’m trying to build my optic train for a Nikon Z6 and an eyepiece on a Celestron 8” SCT (non EdgeHD). As I understand it, the back focus for the telescope is 127mm (5”). If I connect the OTA via the baader short adapter, what adapters do I need on both the camera train and the eyepiece train?

Question by: Jonathan on Jan 14, 2021 6:10:00 PM | 1 Answer(s)

Rating of Question

Lets start with the camera:
- Nikon Z6 - 16mm
- Baader Wide-T-Ring Nikon Z (for Nikon Z bajonet) with D52i to T-2 and S52 # 2408335 (8.3mm)
- optional Reducing piece S52 / M48 # 2958552 (zero length) (for a wider clear aperture; not necessary, if you use T-2 on the telescope side)

The field stop of the eyepiece should be in the same distance from the FlipMirror as the camera sensor. That's ca. 24mm, if you attach the Wide-T-ring directly to the FlipMirror. Then you can use
- Baader Focusing Eyepiece Holder 1¼" / T-2 (T-2 part #08A) # 2458125, 29-35mm for the eyepiece
and
- Baader T-2 / 7.5 mm Extension Tube (T-2 part #25C) for the camera # 1508155
This gives you a working distance of 31,5mm for the camera and 29-35mm for the eyepiece. With this setup, you should reach focus with most eyepieces - usually, the field stop is at the transition between eyepiece body and 1.25" nosepiece, but it can vary. (We all know, that eyepieces are not parfocal...)

The length of the setup is then:
31,5mm for camera (and eyepiece)
59mm for Baader FlipMirror II Star Diagonal # 2458055 when used with T-2
15mm for Baader T Adapter (BTA) for SC and MAK Telescopes (T-2 part #21) T-2 Part #: 21 # 2408160
=> 105,5 mm

Optimum back focus is 127mm, so you need an additional 21.5mm extension, e.g.
Baader VariLock 29, lockable T-2 ExtensionTube 20-29mm with spanner tool (T-2 part #25Y) # 2956929,
if you want to be precise. (a 20mm extension should work good enough, and there is always Set: T-2 Fine-Adjustment rings (0,3 / 0,5 / 1 mm) - Aluminium #2457910) If you want to use the Off Axis Guider, you should place one 211mm-extension in front of the camera and one in front of the eyepiece holder, this will give you more back focus fur the guiding camera. If you don't use the off-axis-port, you can save money and put the extension between flip mirror and telescope. Fortunately, a Schmidt-Cassegrain is a userfriendly telescope, so that you don't have to keep to distance to a tenth of a millimeter.

What accessories are recommended for achieving 133mm backfocus for Celestron Edge HD 8 with a DSLR (with native 55 mm backfocus when used with a t-ring)?

Without any adapters, 55mm flip mirror + 55mm backfocus of a DSLR (with t-ring) leaves 23 mm of optical length left. #2958500B for the SCT connection gives me 7mm + 2mm for the T2 adapter shipped with the mirror. I then have 14mm left to connect the DSLR t-ring to the mirror somehow, correct?

Then if I were to use 2458100 as a focusing eyepiece holder, I'd just need to find T2 extension tubes to achieve the same optical distance to the eyepiece flange, correct?

Question by: WeBMartians on Jan 8, 2021 10:07:00 PM | 1 Answer(s)

Rating of Question

This depends on the field stop position of the eyepiece and the backfocus of the cameras.
For the eyepiece on the upper port, we'd recommend
#2956242 M42i x 0,75-ClickLock (Astro T-2 System) with a height of 36,6mm.
Please note that the upper port is limited by the diameter of the T-2-thread, so it is a little bit less than 40mm, and there will be some vignetting with 2"-eyepieces with long focal lengths.
For the camera, you can use e.g.
#2956220 SC / HD (2")-Clicklock (5" SC, 6" SC/HD, 8" SC/HD and 9¼" SC)
with a height of 47mm.
If I understand the description of ZWO correctly, the larger camera has 6mm of backfocus when used with either T-2 or a 2" nosepiece; the smaller camera should be similar and also include a 2" nosepiece (if doesn't, but has got a female T-thread, you can use Baader 2" nosepiece to T-2 / M48 # 2408150; if it has got only a 1.25" nosepiece, there is Baader Pushfix Reducer 2" to 1¼" # 2408151 with only 1mm of optical height).

We'd recommend to use these two clamps and to determine the focus position of the eyepiece. You shouldn't need to insert it completely into upper port, as that clamp is shorter. If desired, you can add T-2-extensions later to get to the right distance. Or you focus your telescope now with the cameras to find out how much the focus differs between eyepiece and cameras, then you can determine the required T-2-extensions in advance.

For connection to the telescope, we'd need to know the available thread at the telescope. T-2 or M48 work out of the box, for other threads, an adapter would be required.

For further information, please also take a look at this blog post: https://www.baader-planetarium.com/en/blog/using-the-flipmirror-the-correct-working-distances/

Can you please tell me what thread adapter or other adapter I would need to go from the back of the Baader Flip Mirror II, which I think is M48, but please correct me if I am wrong, to a Baader 2" ClickLock for Celestron & Meade SCT?

The reason I am asking is because I purchased several of your products a few days ago. A couple of them being a Baader 2" ClickLock Adapter for 3.25" SCT's and just in case that didn't work I also got the Baader 2" ClickLock for Celestron & Meade. Well, the Baader 2" x 3.25" worked flawlessly. Now I'm left with an expensive Baader 2" ClickLock for Celestron & Meade SCT.

So, what I'd like to do is mount the Baader 2" ClickLock for Celestron & Meade SCT on to the back of the Baader Flip Mirror II to make it easier to mount my DSLR to the back of the flip mirror, but I am unsure of the specific thread adapter/s I would need to make it work. So, I need to go from the back of the Baader Flip Mirror II to the Baader 2" ClickLock for Celestron & Meade SCT.

Can you please help me figure out what part or parts I will need to make it work? Do you have a thread adapter to make this work and if you do can you please provide me with the Baader part number/s?

Any help you can offer would be very much appreciated.

Thank you.

If we identify your mentioned left-over ClickLock as our 2" SC/HD clamp #2956220, then this features a female 2" SC thread. The FlipMirror on the other hand has no fixed adapters on either side, only an as-delivered state. So we can't tell for sure which adapter you're using on the back side and which you have maybe left for use.
If you indeed have an M48 male thread on the backside, you can use the 2" male / M48 female adapter #2454834 to mount the SC clamp:
https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/m48-adapter-system/2%22a--m48i-zero-length-reducing-piece-(no-optical-height).html
If you have a T-2 female thread, you can use the 2" male / T-2 male adapter #1508035
https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/2-inch-sc-thread/baader-adapter-2%22-(male)--t-2-(male).html
And for a T-2 male thread you could use the 2" male / T-2 female adapter #2958242
https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/2-inch-sc-thread/baader-expansion-ring-2%22at-2i-with-1mm-optical-path-length-(t-2-part-28).html

The FlipMirror is really a very versatile tool. Please make sure to read the detailed instruction manual carefully to get yourself familiar with all the included adapters and thus all the adaptation options. https://www.baader-planetarium.com/en/downloads/dl/file/id/1568/product/4285/instruction_manual_baader_flipmirror_ii_star_diagonal.pdf

Dear Baader,

After looking over the instruction manual you sent me the link for now this looks like I need to go into a female S52 thread on the back of the Flip Mirror II. Or whatever the native thread is without any of the adapter rings that come with the Flip Mirror II. I have all of the adapter thread rings removed and so now I need to go from whatever that female thread is on the back of the Flip Mirror II to your 2" SC/HD clamp #2956220, with this female 2" SC thread.

I apologize for not asking my question in a more definitive manner. I hope it is more clear now that I want to go from the back of the Flip Mirror II with no adapter rings installed to the 2" SC/HD Clamp #2956220 with the 2" female SC tthread. So I need a Baader adapter with 2 different male threads on it. I'm hoping now you can tell me the correct adapter ring I need to use since I rephrased my question.

I'm sorry for repeating so much but I just want to make sure there are no misunderstandings so I'm not buying any unnecessary parts.

As always Baader, thank you for your help.

I've just ordered a Celestron 9.25 XLT telescope for planetary viewing and astrophotography. I think adding a Baader Flip Mirror for my imaging train would be quite convenient. With the flip mirror I will probably only use an eyepiece on one end and a Barlow, UV/IR cut filter, an ADC and a planetary camera on the other end. All this equipment is 1.25 inch. Will I need extra accessories, like a click-lock or specific kinds of threads, to attach everything to the scope and mirror? If so, what kinds would work? Thank you.

Question by: Doug Berger on Oct 30, 2022 5:26:00 PM | 1 Answer(s)

Rating of Question

This depends... The Schmidt-Cassegrains usually offer either a 1.25" visual back or a 2" star diagonal which is screwed onto the 2" (standard SCT) or 3.3" (EdgeHD) thread at the back of the telescope.
We would recommend to replace it with #2956220 SC / HD (2")-Clicklock (5" SC, 6" SC/HD, 8" SC/HD and 9¼" SC) so that you can use any standard accessories - and easily rotate them into a conveniant position.
Then, you can attach
Baader M48 extension tube 30 mm / 2" nosepiece with Safety Kerfs # 2958630
to the Flip Mirror and use it with the telescope.

The Flip Mirror itself has got T-2-threads on both ends. For use with Barlow and ADC, it is probably the best if you use T-2-eyepiece clamps on both ports. There are several clamps available: https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/eyepiece-clamps.html?filter_threads_lenssided=536 As the position of the ADC should be orientated on the horizon, it is better to use a clamp than to screw it directly onto the FlipMirror without an option to rotate it.

As the magnification factor of the Barlow depends on its distance to the sensor, it should probably be mounted behind the Flip Mirror. Together with the ADC, this will move the focus position, but it is hard to say how much - so you will probably need some T-2-extensions to reach the same focus position with the eyepiece on the upper port, too, but you'll have to try out how many T-2-extensions you will need.

I already own a Celestron C6 SC XLT with a much appreciated Hyperion Mark IV zoom. I would like to replace the stock diagonal with a Baader FlipMirror II.

The idea would be to

- permanently connect the FlipMirror II to the telescope using the "Baader SCT T Adaptor Ultra Short 10mm Optical Length"
The space available to rotate the flipmirror for screwing it in seems not enough on the C6, but I have seen that it is possible to screw it in without the telescope focus knob getting in the way if the rubber jacket of the knob is temporarily removed.
- connect a DSLR to the straight FlipMirror output (I already have a low profile Canon T2 adapter)
- use my Hyperion Zoom MkIV on the angled top output, either directly screwed in or through a baader 2" clicklock since I might use other Eyepieces

Besides flipmirror, SCT adapter and clicklock what other components do I need to have for having the DSLR and the eyepieces at the same focal distance from the scope?

In order to use the OAG port at the base of the flip mirror, the prism can only go so high before it will hit the mirror when ‘down’. If your connection to the telescope relied on a 1.25” nosepiece rather than a 2” / T2 /M48 connection, would the light ever reach the prism as it would be too low to pick up any light?

To attach the BFM-II to a 2" eyepiece clamp, you can use 2" / S52 Nosepiece # 2958551

Please note that the upper port is restricted by the T-2-thread and the diameter of the diagonal. The usable field is 32mm, equal to our 32mm T-2 prism diagonals.

You can screw a standard DSLR with standard T-ring directly to the back of the BFM-II. There are small set screws to adjust the rotation of the camera with a screw driver or an allen key. The distance from the sensor to the flip mirror is then 55mm (the standard flange distance of T-2).

On the upper port, you can use the M42i x 0.75-ClickLock (Astro T-2 System) #2956242 with a height of 36,6mm. Then you need a T-2-extension of ca. 18mm to bring eyepiece and camera to the same focal distance. It might be the best to use the shorter Baader T-2 / 15 mm Extension Tube (T-2 part #25A) # 1508154 and let the eyepiece stick out a little bit, or to use a 7.5mm or 15mm extension between camera and flip mirror and a Vari Lock for the eyepiece holder. We can't give a final anser to this, because not all eyepieces have the same focus position - it is often at the top of the 2" nose piece, but it may vary. For 1.25" eyepieces, you have to take the length of the 1.25"-adapter into account, too. The shortest solution is Baader Pushfix Reducer 2" to 1¼" (T-2 part #15a) # 2408151.

For more about this, please take a look at this article: https://www.baader-planetarium.com/en/blog/using-the-flipmirror-the-correct-working-distances/

Description

Details

Baader FlipMirror II Star Diagonal

Various ports – variable work

Telescope auxillary instruments cover a wide range of interests, from a sole eyepiece, via camera use, to high end spectroscopy. Unfortunately every telescope just features one exit port. This causes relentless manual exchange of parts in the dark, causing huge time loss, wear on the parts - and "nerves". And whenever you start controlling your telescope remotely - the single port becomes a painful reality.

Improving workflow, especially during astrophotography is the goal set out for the BFM II. This is not just a simple flip mirror but much more, as there are three ports to be put into action.

BFM II makes your single telescope port variable - to suit your various interests.

The FlipMirror II Star Diagonal allows a variety of permanent adaptations to your telescope 1 . Use the rotary knob 2 to switch between the rear port 3 and the top port 4; you can use an optional toothed belt to operate it with a motor (not included). An autoguider or a calibration lamp can be connected to the bottom port 5.

General Function of the FlipMirror II Star Diagonal

The BFM II lets you switch between a straight light path (Position A) for a camera or other measuring instruments and an angled light path (Position B), e.g.
for an eyepiece. The following figure shows how it works. In addition, a calibration lamp for spectrographs or an Off-Axis-Guider pickoff-prism (that is not affected by the mirror position) can be connected at the AUX-port on the bottom

Scope of Delivery of the Baader FlipMirror II Star Diagonal:

Baader FlipMirror II Star Diagonal – with fine-optically polished, movable mirror
Laterally adjustable T-2a top ring
