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.
Important Care Tips for astronomical instruments
Please, observe the following guidelines to protect your telescope/mount and avoid damage or even loss of warranty.
I have a Williams Optics FLT-132 and a ZWO ASI183MC Pro CMOS astro camera. Can I attach the astro camera (which will also use ASIAIR for GoTo function) to the back of the flip mirror and then an eye piece to the top of the flip mirror, to simultaneously have the ability to take images of an object as well as see it visually in real time through the eyepiece?
Answer rated: 0Simultaniously taking photos and observe will not work. You can do either/or, not both at the same time. Because the light either hits the mirror and goes to the eyepiece - or it goes straight through the Flip Mirror housing and hit the sensor of your camera.Answer by: Baader Web Team (Admin) on Mar 31, 2023 3:49:00 PMRated: 0
Should I expect good performance when using a High speed SII filter with a color ASI2600mc camera and Hyperstar? Or only in mono cameras?
Answer rated: 0The filter itself will work as desired. But SII is in the deep red, at around 672nm. So, with a colour camera with RGGB Bayer matrix, only one fourth of the pixels are sensitive for red. That's why a monochrome camera will always be much more sensitive for narrowband photography: It collects the photons with all the pixels, and not only with those which are sensitive for red.
RASA and Hyperstar are more fun with a colour camera and a broadband filter like the new UHC-L (which can be pretty good against LED lamps), as you can then use the whole sensor in one image and don't need to swap filters. If you really want to go into narrowband photography (no matter with which filters) due to high light pollution, a monochrome camera is superior.Answer by: Baader Web Team (Admin) on Mar 31, 2023 9:00:00 AMRated: 0

Hi, do you make an L extreme filter that will fit a Canon L lens with 52mm drop in filter?
The actual glass in the existing filter looks to be around 43mm wide.
Answer rated: 0Our 2" Filters have a clear aperture of 46mm. Our equivalent to the L-extreme filter would be our UHC-L Ultra L-Booster Filter: https://www.baader-planetarium.com/en/baader-uhc-l-ultra-l-booster-filter.html
For adapting any cell mounted Baader 2 inch Filter onto a camera lens with 52mm front filter thread you will need:

Based on the SP54 thread, we offer many more adapters for various camera threads, our so-called Hyperion DT-rings. https://www.baader-planetarium.com/en/catalogsearch/result/?q=sp54

Dear Baader, is possible to use the reducer for H alpha visual observations or isnjust a photographic togliere? Thanks!
Answer rated: -1Its more a photographic tool. You can use it visually but its not very satisfying because you see an obstruction on the outside and the image is more concentrated and therefore brighter which affects the visual surface contrastAnswer by: Baader Web Team (Admin) on Mar 27, 2023 8:12:00 AMBaader Planetarium GmbH
