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?

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?

Rating of Question

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. Please read more about the mechanical and optical properties of our BBHS-diagonals, as well as our marketing philosophy, to not participate in the usual number competition here: http://www.baader-planetarium.com/en/blog/baader-bbhs-reflective-properties/

Does the mirror diagonal reflect or pass through the UV/IR into the diagonal aluminum housing?

I want to use a petzval refractor for H-alpha solar observing with a dedicated solar filter. It is in general recommended not to use an UV/IR cut filter before the diagonal, since UV/IR reflections can come to focus in the petzval rear glass elements and harm the scope. If it rejects UV/IR by passing UV/IR into the diagonal housing, this is a big sales argument for the dielectric mirror when using a petzval scope.

Best regards
Thomas

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.

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?

I would like to connect an adapter having a male M48x0.75 thread directly to the diagonal with the nosepiece removed (such as the TSFLAT2). The diagonal with nosepiece removed has an SCT female thread, so I need an adapter that will change the SCT female thread to an M48x0.75 female thread. Many people are considering this.

Would either of these adapters work for this purpose? Or would you recommend another?

Try as I might, I cannot remove just the 2" nosepiece from the S58 dovetail: it is as though it is permanently joined to the S58 dovetail, and the whole assembly screws off. Am I doing something wrong? And if just the 2" nosepiece cannot be removed after all, Is it possible to obtain the S58 dovetail used here separately?

Question by: Carl Hostetter on May 3, 2023 8:06:00 AM | 2 Answer(s)

Rating of Question

The 2" nosepiece is surely not permanently joined to the S58/M55 adapter, but it is possible that it is tightened very (too) hard. When unscrewed together with the S58 adapter, you could try to hold the S58 adapter with some thick rubber and then try again to loosen the nosepiece. If that doesn't work we could also loosen it for you depending on where you're from, or you might contact your dealer.
Although the S58 adapter is normally not sold individually, that would also be an option if everything else fails.

I bought this product a few days ago but don't want to use it in its native configuration. I will take off the nosepiece and the ClickLock adapter.

However, I want to use the ClickLock adapter elsewhere in my setup but will need the 2" SCT adapter (2"/S58) provided with the ClickLock SC/HD (2") clamp (C5" - C9¼") #2956220.

I don't want the M55/2"/S58 ring that comes twice with this diagonal but the 2"/S58 ring (without M55 threads) that comes with ClickLock SC/HD (2") #2956220.

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.

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.
