Adapters & Imaging Accessories

A reducers does not only reduce the focal length, but also the image circle: The beam of light is much steeper behind the reducer than in ffront of it. For example, the 0.7x EdgeHD reducer #94242 for the 8" EdgeHD illuminates only an image circle of approximately 30mm for APS-C-cameras . The prism of an Off-Axis-Guider like the one in the FlipMirror II is positioned in such a way that it doesn't block a full-frame camera sensor. But if the light beam of the telescope becomes too small, the prism is in the darkness outside of the telescope's light path. Then, even an extremely sensitive guiding camera can't see any stars. In this case, an Off-Axis-Guider can only be used in front of the reducer – if this is possible by the optical design of reducer and telescope. (The image circle e.g. of an EdgeHD 925 with reducer is already much larger.)

To answer this question, we need to know the backfocus of your telescope. If it is not given in the instructions, you need to measure it.
Eitherpoint it at the moon and put a piece of of paper behind it, so that you can see a sharp image - the distance between paper and telescope is the back focus. Or, if you already have a focuser, point it at the stars with either a camera attached or star diagonal and eyepiece, and measure the length of your focuser. Pleas note that eyepieces, DSLRs and astronomical cameras all have different optical lengths! A DSLR requires 55mm of backfocus, a CCD-camera often only about 1cm, and a 2" star diagonal about 11cm - so may work with an eyepiece and star diagonal without extensions, while a CCD-camera may require an extension.

The SC-version of the Steeltrack has got a focus travel of 30mm, so if you are switching between a 2" star diagonal and an astronomical CCD-camera, you will require an extension. The possible minimum heights are as follows
as supplied, incl. 2" clamp: 93 mm
with optional S58 direct-thread adapters: 80 mm

The RT-version for refractors may fit too, it has got a longer focus travel of 80mm and the following minimum lengths:
as supplied, incl. 2" clamp: 70 mm
with optional S58 direct-thread adapters: 59 mm
with optional S58-ClickLock clamp: 89 mm
You have to check the manual to see if one of the adapter threads matches your telescope, or if you need to manufacture a special adapter.

The SC version has got a shorter focus travel as you are more flexible with a Schmidt-Cassegrain and its moveable ain mirror than with a refractor telescope.

Baader Adapter 2" (male) / T-2 (male) [Part # 1508035] should work, this is the same solution which we use for our Herschel wedge, as described on page 17/18 of the MaxBright manual: https://www.baader-planetarium.com/en/downloads/dl/file/id/1614/product/4317/manual_baader_maxbrightr_ii_binoviewer.pdf
A quick changer is recommended, so that you can more easily rotate the binoviewer into a conveniant position.

If you want to attach the ClickLock 2" clamp to the 2" adapter please choose #2956220 SC / HD (2")-Clicklock (5" SC, 6" SC/HD, 8" SC/HD and 9¼" SC). Otherwise, if you want to attach the clamp directly to the big 3,3" thread on the rear end of your telescope, choose #2956233 SCL (3,3")-ClickLock (9¼" HD, 11" SC/HD and 14" SC/HD)

Unfortunately we do not know the Meade telescopes finderscope holder. But if its a standard one similar to Celestron, one of the SkySurfers bases will fit. You can see here in the manual the scope of delivery https://www.baader-planetarium.com/en/downloads/dl/file/id/1487/product/1748/manual_for_the_baader_skysurfer_iii.pdf
