Pentax
Refraktoren von PENTAX
Pentax refractors are specialists for one thing above all: They are excellent optics for photography. In addition, the refractors have a very large field of view which is free of aberrations - even without additional field flatteners. This was certainly a convincing argument for Pentax refractors, especially if you think of the always-increasing chip-size of modern digital cameras.
Unfortunately, PENTAX has completely stopped the production of astronomical refractor telescopes. Unfortunately, we cannot order any parts, nor do we have any remaining telescopes in stock.
We are still producing adapters from Baader Planetarium for the Pentax system. With the Baader M68 system we offer an adapter solution for the eyepiece side of Pentax refractors, which allows the use of the complete range of Baader accessories.
On our www.baader-planetarium.de website we had a presentation of the PENTAX refractors, which we would like to make available to you here as a reference in PDF form (sorry, German language only).

2" MPCC Mark III (Multi-Purpose Coma Corrector for Newtons)
Can I use the MPCC Mark III coma corrector with a Baader Hyperion Universal Zoom Mark IV, 8-24mm eyepiece and/or Baader zero-tolerance protective Canon DSLR T-Ring T-2/M48 ?
Answer rated: 0You 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

Baader Wide-T-Ring Fujifilm X with D52i to T-2 and S52
I'm quite confused, but i just want to connect the older fuji DX LENS. X MOUNT to my new fuji FX BOBY. JUST wonder why any thin ring mount ？don'T quite the thick adepter.
Your kind advice will be deeply appreciated.
Answer rated: 0The 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.Answer by: Baader Web Team (Admin) on Sep 16, 2019 8:49:00 AMRated: 0

Baader 2"/90° Astro Amici-Prism with BBHS ® coating
Is a roof line spike visible using the 2" Baader Amici prism in the telescope at low or high power? I plan to use the prism for astrophotography and really need the short back focus that this diagonal provides.
Answer rated: 0We 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.Answer by: Baader Web Team (Admin) on Sep 16, 2019 9:14:00 AMRated: 0

Baader 10mm Hyperion 68° Modular Eyepiece
I have a ZWO ASI290MC planetary camera that I would like to attach to my Baader Hyperion 1.25"-2" on a Celestron Nexstar 6SE. What spacing adapter (M43) would I need to attach the ASI290 to the Hyperion 10 mm in order to achieve focus? Would I achieve greater magnification for planetary imaging if I were to attach the ASI290 camera to the Hyperion 10 mm eyepiece instead of using a 2X Barlow?
Answer rated: 0Please 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 # 2458200Answer by: Baader Web Team (Admin) on Sep 11, 2019 8:48:00 AM
