Product Questions

I have a Celestron Edge HD 8" SCT. After a few months using the 40mm kit eyepiece, I'm looking to purchase a couple of Hyperion eyepieces. What ClickLock components would be required to mount this?

Question by: Greg Russell on Apr 25, 2017 2:58:00 PM | 1 Answer(s)

Is the 2" ClickLock Diagonal Mirror (# 2956100) threaded for standard 2" filters? Thanks!

Question by: Marco Zanchetta on Oct 16, 2016 6:12:00 PM | 1 Answer(s)

How secure is the nosepiece when coupled to the diagonal body? Is there any risk of it loosening when subjected to heavy loads with the diagonal oriented horizontally?

Question by: Aaron D. on Apr 8, 2018 3:29:00 AM | 1 Answer(s)

Is the housing for this diagonal CNC machined? And what features are there that ensure proper alignment of the mirror? What are the features of the mirror glass?

Question by: John Aviste on Sep 8, 2016 8:02:00 PM | 1 Answer(s)

The mirror seat of the diagonal body is machined, to provide a defined position.
We do regard the mirror substrate of our dielectric diagonals a proprietory information. As you may have heard, a dielectric coating with as much as 50 coating layers can extend an enormous amount of stress onto the mirror substrate. Many proudly offered dielectric mirrors suffer under "power" - means the surface bends under the coating stress and over time develops a very weak spherical shape. For this reason we use a hardened variety of borosilicate glass, which can sustain the plane polished surface to remain in perfect order. Admittedly this substrate has somewhat larger index of expansion and does take longer to regain its optical shape when subjected to large temperature differences - but only when compared to our BBHS mirror-diagonals which feature a hard-silver coated glass-ceramics (Astro-Sitall) as substrate.
However - we had extensively tested this combo of coating and substrate to be a perfect match for our dielectric diagonals - especially ensuring a longlived product that does not change in optical quality over time.

Can a UFC be inserted between the 2" barrel nosepiece and the diagonal body (point A in this discussion: https://www.baader-planetarium.com/en/blog/optical-tube-lengths-of-clicklock-mirror-diagonal) by using #2459128 and #2459120 for the telescope and camera adapters on the UFC respectively?

I have a Celestron Nexstar 6SE SCT. Is the 2” diagonal compatible? Do I need adapters, which one?

Question by: Etienne Ali on Oct 4, 2020 4:12:00 AM | 1 Answer(s)

I have a 2” clicklock star diagonal which has had the 2” telescope side nosepiece damaged. Is it possible to purchase a new 2” nosepiece separately?

John.

Question by: John Bentley on Nov 19, 2020 2:01:00 PM | 1 Answer(s)

I have a Celestron CPC 925. I have just bought the Baader 2 inch Clicklock Dialectric diagonal. Your user guide says that if I unscrew the Kerf nosepiece the diagonal has two more useful connections: An SCT thread and a S58 dovetail. However, when I try to screw the diagonal body onto my SCT it will only screw on half a turn. The threads seem to be diffferent. what am I doing wrong? How do I access the SCT thread on the diagonal?

The Hyperion 17 baader eyepiece has the stop of the 2-inch barrel placed at 51,5mm. This eyepiece can be inserted into the 2-inch opening of the diagonal baader clicklock, without touching the diagonal mirror? Thanks for everything!

Question by: Eric on May 27, 2020 8:10:00 PM | 1 Answer(s)

I have a Baader 2" click lock diagonal (#2956100) directly mounted to a SCT with a Baader 2" Nexstar locking ring. I just received a Baader 2" filter, but can find no way to insert this into the optical path, before or after the mirror. Is there an adapter available for this. Ideally, I would like to leave the filter in places instead of moving it from one eyepiece to another.

Can I use an UV/IR-Cut filter or the BBHS mirror in front of an H-Alpha or Calcium Solar Filter? Do you recommend the 2" BBHS or 2" Clicklock Mirror for solar observation?

-16

Question by: Enrique V. on Sep 26, 2016 3:04:00 PM | 1 Answer(s)

If you want to observe the sun in H-Alpha, we recommend the standard dielectrical Clicklock mirror (# 2956100) in combination with a suitable filter combination, because the dielectrical filter reflects less radiation below 380nm and above 740nm. This way, the mirror can reduce the strain on the following filters at least a little bit.Please do also use an energy rejection filter in front of the telescope to reduce the strain on the filters as much as possible.

We highly advise against visual calcium observations of the sun - the 397nm of Calcium are already ultraviolet radiation, and UV-radiation can cause phototoxic reactions which can harm your eyes. In addition, even young people can't see these wavelengths very good, and sensitivity decreases with the age. Because of this, the eye doesn't feel if the intensity is much too high. If you now try to increase the amount of radiation (e.g. with another mirror) to achieve a brighter image, you will increase the risk for eye damage. According to the newest norms for eye safety and to ophtalmologist conclusions, the sun must not be observed visualy at 397nm.

We highly advise to only observe the sun in calcium photographically, then you also do not need a star diagonal. We can't understand why some manufacturers promote these calcium-filters for visual observations.

We also advise against placing a filter so close to the focus - any energy rejection filter belongs in front of the front lens, even if this sets high demands to the quality of such a large filter. Placing the filter close to the focus will save money, because you can use a much smaller filter, be we absolutely can't recommend it - because of our own conscience as well as because of EU-regulations. The filter would receive all the energy collected by the front lens. We can only recommend putting the energy rejection in front of the front lens, which is the ethically and technically correct method.

Optical tube lengths of 2" Clicklock and BBHS mirror diagonals

Recently we received the following questions on our 2" Clicklock Diagonal Mirror and wanted to answer including the below illustrations for other customers: Please note: all of the below information is also valid for our 2" BBHS mirror and prism diagonals (with slight differences in the specifiations such as optical tube lengths – please compare with specs on the product pages). According to image below is the optical path mentioned in technical data (112mm for #2956100 and 109mm for #2956100Z) measured along optical axis from point A to B or point A to C? what is the dimension from point B to C? Can 2” barrel (at point A) be removed from #2956100 and exchanged with another accessory (is it available?) to change the diagonal to #2956100Z (M68x1 thread)? Please note below our answer and adjusted graphic: The optical path of 112mm is measured A to C. The lightway from A to B would be ~71,5mm. Please note that the final endpoint of B is 3,5mm outside of the prism body (as illustrated in the below graphic), it looks just like point A in your drawing The Dimension from B to C (height of the SC-ClickLock) is 44mm. It is overlapping the...

Overview and Recommended Use: Baader Star Diagonals

The most versatile tools: Baader Star Diagonals (T-2 and 2") Manual and Recommended Use A Baader star diagonal (both prisms and mirrors) can show you impressive images for a lifetime and offers more connection and configuration options than standard star diagonals. Baader Planetarium's star diagonals not only offer the highest mechanical and optical quality, but also have the additional advantage of being part of a large, modular system. They enable very short adaptations as well as threads for direct connections to a telescope or a Baader focuser, as well as adaptation to a wide range of threads for torsion-free use with heavy or long accessories, such as binoviewers. Decades of customer feedback led Baader Planetarium to create a seemingly overwhelming amount of adapters. But each adapter has its purpose. This is the reason why you can always find the optical length of each part in the product description, so that you can find the best solution for your needs. To get the most out of them, we recommend that you spend a few minutes reading this brochure. On the following pages you will find a guide on how to choose coating and star diagonal type an overview of the different...
