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).

Baader FlipMirror II Star Diagonal
I cannot get the image in the eyepiece to center. I'm using the Baader Focusing Eyepiece holder. I have moved the adjustable T2 ring to its limit, but the image when centered in the camera is at the edge of the field of the eyepiece. Ideas?
Answer rated: 0You probably need to adjust the two brass pins on which the mirror rests in its lower position. This way, you can move the image along the optical axis of the telescope (either closer to the telescope or to the camera).
To test this, take a look through the eyepiece and move the mirror slightly up - if the star moves in the desired direction (or contrary to it), then you need to adjust the brass pins. Please see page 11 in the manual (chapter 3 - Adjusting the mirror). If it moves sideways instead, things get complicated. But that's most probably the solution.Answer by: Baader Web Team (Admin) on Mar 25, 2020 10:58:00 AMRated: 0

Baader FlipMirror II Star Diagonal
In order to use the OAG port at the base of the flip mirror, the prism can only go so high before it will hit the mirror when ‘down’. If your connection to the telescope relied on a 1.25” nosepiece rather than a 2” / T2 /M48 connection, would the light ever reach the prism as it would be too low to pick up any light?
Answer rated: 0In its downward position, the mirror has got a length of ca. 2,5cm, so there are only 2-3mm for an autoguider prism. This might just work, but we wouldn't recommend (and be at peace with ourselfes).
To be honest, autoguiding is usually used for larger sensors which would be obstructed by a 1,25"-focuser anyway, and most focusers which are strong enough for a flip mirror, a camera, a guiding camera and maybe even an eyepiece are 2"-focusers, so we preferred a larger mirror.Answer by: Baader Web Team (Admin) on Mar 20, 2020 2:48:00 PMRated: 0

2" MPCC Mark III (Multi-Purpose Coma Corrector for Newtons)
Can the MPCC be used with the Hyperion Zoom 2.25x Barlow lens for imaging? I can use the Focusing Eyepiece Holder and Varilock combination to connect them, but will this actually work and if so, what length should I set between the MPCC and Barlow?
Answer rated: -2The MPCC is an tool for Deep Sky photography with Newtonian telescopes. It not designed for use with an Barlow lens that you normally use for high power photos or visual observations mainly of Solar System objects. The barlow lens would magnify the middle of the field wich is mostly coma free anyway. We suggest to work with the Hyperion Zoom and Barlow lens and without MPCC.Answer by: Baader Web Team (Admin) on Mar 13, 2020 2:40:00 PM
