Cameras

You can use every 1.25" eyepiece where the position of the field stop is known. You can find the data in this PDF: https://www.baader-planetarium.com/en/downloads/dl/file/id/357/product/3117/hyperion_universal_zoom_mark_iv_specifications_drawing_and_technical_data.pdf
It depends on the configuration of the Mark IV, how the MPCC must be fonfigurated to be set to 55mm.

For the Canon Protective T-Ring, you need Baader M48 Spacer Ring for MPCC III / Protective EOS T-Ring # 2458405 as described on page 6 of the manual: https://www.baader-planetarium.com/en/downloads/dl/file/id/483/product/3004/mpcc_mark_iii_instruction_manual.pdf

The outer diameter of our 1.25" filters (including the cell mount) is 31 mm.

The Wide T-Rings are made for telescopes where a wide aperture is desired and you often have to fight for each mm.
So, this adapter gives you a flange distance tor T-2 of 26mm instead of the 55mm which are required for old T-2-lenses. So, it will not work with T-2 camera lenses without an additional spacer.

We do not recommend Amiciprisms for astrophotography at all. The problem is the colour fringing and contrast loss that happens because of 3x internal reflexion. Even highest quality Amici Prisms do have these effects wich are visually not disturbing and barely visible. But photo quality will decrease significantly. Genereally it is recommened to have a straight beam path for Astrophotography. The less glass is in between the collecting optical element (mirror or lens) and the camera, the better it is.

Please take a look at our Digiscoping-PDF at https://www.baader-planetarium.com/en/downloads/dl/file/id/444/product/1210/digiscoping_camera_adaptations_for_afocal_photography_and_eyepiece_projection.pdf where we describe several options to attach a camera or video module.

You need some distance between camera and eyepiece to avoid distortions at the edges; but with a smaller sensor, you can get closer. You'll usually achieve higher magnifications than with a Barlow lens; the formulas for calculating the effective focal lengths are inside of the PDF.

For large sensor and really high magnifications, we recommend the FFC # 2458200
