Mit diesem Adapter kann ich die gesamte Länge des Backfokus für Einbauten nutzen. Perfekt!

Well made. What is not clear is that it is made of 3 components - look very closely at the image. This allows you to attach it to the SCT telescope then rotate your rig to suit your needs. A great product although could be less expensive.

Will I be able to screw the Baader VariLock 46: T-2 Extension Tube directly onto this adapter to achieve precise back focus between my Meade lx90 SCT and my Canon EOS camera?

- Yes, the VariLock fits between the Ultrashort adapter and any T-ring for your DSLR.Baader Web Team / February 8, 202400

I see removal holes in this adapter for what looks like a spanner wrench. Do you sell a spanner wrench to release the inner ring of this adapter?

- We do have Adjustable pin type face wrench ø 2mm, # 2450062, but it will not fit into this adapter. However, there are several manufacturers of tools to open and repair camera lenses - with these keywords or "Camera Lens repair tool", you should easily find a suitable tool to reach these holes.Baader Web Team / March 23, 202300

what do i use to connect baader planetarium flip mirror to the back of celestron 8se and what is the back focus for zwo asi294mc-pro camera. zwo says 55mm how do i get this using baader flip mirror device????
stephen / January 2, 20231 Answer
- The C8 has got an optimal working distance of 5" or 12,7cm from the SC-thread. The camera has got a flange focal length of 17.5mm with the included 11mm T-2-ring which is included with the camera (there are other adapters included to achieve the 55mm which are standard for old T-2-lenses and most T-2-reducers/flatteners or a DSLR) You can achieve the perfect distance e.g. with: Baader SC / HD Ultra Short T-Adaptor 9mm # 2958500B T-2 Fine-Adjustment ring 1mm (gold) - Aluminium #2457913 Baader T-2 / 40 mm Extension Tube (T-2 part #25B) # 1508153 FlipMirror in T-2-configuration - length 59mm T-2 Fine-Adjustment ring 0.5mm (red) - Aluminium #2457912 Camera - 17.5mmBaader Web Team / January 5, 202300

If I were to attach this to the back of my celestron 9” edge hd then attach my Baader flipmirror, would I be able to get correct rotational alignment/adjustment of the flipmirror?
David / October 13, 20221 Answer
- You can always fix the FlipMirror in any desired rotational position, no matter which adapters are attached to it. Simply loosen the screws highlighted on page 5 of the manual, rotate the flipmirror to the desired position and tighten them again. https://www.baader-planetarium.com/en/downloads/dl/file/id/1568/product/4285/instruction_manual_baader_flipmirror_ii_star_diagonal.pdfBaader Web Team / October 14, 202210

The 2", 24 turns-per-inch thread does not appear to be a standard thread in any of the UNF, UNC or Whitworth lists. All threads have dimensional tolerances (permitted dimensional deviations). The standards, such as ISO 965 for metric threads or ASME/ANSI B1.1 for Unified National threads, specify these. How are the permitted dimensional deviations defined for this product please? My reason for asking is that I want to be very sure that £2000 worth of camera equipment held in place by this product will not fall off. The consequences could be serious.

- That’s great, thank you. My adaptor arrived this morning and I have attached it to the telescope. It works just fine, does not “jiggle” or “wiggle” and I applied as much force as I dared to try to pull it off. It didn’t even almost pull off. I am pleased to hear that you and Celestron have shared a detailed specification. I don’t need to know what’s in it. The fact that there is one is enough to reassure me. Thank you very much.Dr. Jane Clark / August 16, 202220
- We do cut this thread according to the Celestron directives which are not to be published. We are authorized Celestron Distributor since 45 years and please be restassured that we know how to cut that 2" thread - as long as it will be fitted onto a Celestron-OTA.Baader Web Team / August 12, 202200
