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).
There are no products matching the selection.

2" BDS-RT Baader Diamond Steeltrack Focuser
Do you have an adapter for the Explore Scientific ED102 Triplet APO for the Baader Planetarium 2 Inch Steeltrack Crayford?
Answer rated: 0Obviously this telescope you can get in three different versions (Essential Line, Professional Line, High-End Line) with different focusers.
We don´t know what type do you have. Maybe ask a dealer who is selling this telescope to find out out what thread is in use to connect the
focuser. So far there are so many different brands and types on the marked we cannot have all informations about. Unfortunately Explore Scientific
doesn´t offer those necessary data. A data sheet for the Steeltrack you can find here:

Baader MaxBright® II Binoviewer with case
What is the lightpath length of this binoviewer?
Answer rated: 2The value of 110 mm +/- ca. 1mm (same as in the Mark V) was measured on a refractor. The small error margin of the measurement is caused mainly because of the diopter adjustment. Because of the not-standardized position of the field stop in eyepieces, it is always a good idea to plan with a security margin of some more millimeters.Answer by: Baader Web Team (Admin) on Feb 19, 2020 8:53:00 AMRated: 0

2" MPCC Mark III (Multi-Purpose Coma Corrector for Newtons)
Is it possible to connect the MPCC to a DT RING SP54 /M52 ?
If yes which intermediate ring should I use.?
Thank you
Answer rated: 0You can use
Baader Hyperion DT-Ring SP54/M52 for DTAdapter II&III and Hyperion Eyepieces # 2958052
to get from SP54(female) to T-2 (female), then you can screw this adapter to the T-2-thread of the MPCC and have a male M52-thread on the camera/eyepiece side of the MPCC.
But please do not ask about the correct distances for a camera lens, we never tested this under the stars.

Baader C-Mount Canon EOS
I want to attach my Celestron Neximage 10 to my Canon eos lenses. Canon eos cameras optical distance from the back of lens to the sensor is 44mm. The distance of this adapter is 26mm and the back focus of my Neximage is 13.1 mm. Would I need an extension tube 5 mm long to achieve focus? Thank you, David.
Answer rated: 0Yes - even if you might be able to reach focus without the 5mm extension, the sensor would be so far away from the distance for which the lens is designed, that the quality would suffer.
So, we highly recommend the extension.Answer by: Baader Web Team (Admin) on Feb 12, 2020 9:43:00 AMRated: 0

Baader Short Pillar III w/o Flange Adapter
What is the recommended weight capacity of the pillar?
Answer rated: -1This depends on the connection to the pillar below. The short pillar itself is made of massive steel, this part itself can easily handle ~100kg of weight, the question is how solidly you are mounting it onto your pillar.Answer by: Baader Web Team (Admin) on Feb 11, 2020 12:19:00 PM
