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.

Baader Single Polarizing Filter
I use 1 1/4 eyepieces on a SOlar wedge. For nighttime observing, I use a T2 Zeiss prism diagonal with a 2" nosepiece (which sits in a 2" focuser). I already have a 1 1/4 " polarising filter which fits onto my eyepieces. Can I combine this with a 2" polarising filter, to be put before the prism, and use the combination as a variable polariser for lunar observation (i.e. one polarising filter before the prism and a second one after the prism, and conveniently rotating the eyepiece to get the desired dimming)? This would be very practical, if it works, but will this setup be less good than a dedicated 1 1/4 inch variable polariser?
Answer rated: 0Yes, sure, this works!Answer by: Baader Web Team (Admin) on Mar 1, 2021 11:55:00 AMRated: -1

Baader Sky Surfer V (Night & Day Design) Red-Dot-Finder
I would like to attach the Sky Surfer V to an Orion 180mm Mak-Cass. The spacing between the available finder scope screws is 0.75 inches (approximately 19mm). This spacing appears to be too narrow for the Baader Standard Base that comes with the Sky Surfer V. Is it acceptable to use the center hole plus one of the slots to attach the base to the Mak-Cass or to maybe use only the center hole? If neither approach is acceptable do you have a dovetail mounting base that will work with a 19mm attachment screw spacing?
Answer rated: 0It is no problem to attach the base to a round tube only with the central screw - the form of the base makes it impossible that it rotates on the telescope, and one screw is sufficient to hold the weight.
Only on a flat surface or if you can't tighten the screws, you will need two screws.Answer by: Baader Web Team (Admin) on Feb 26, 2021 10:27:00 AM
