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?

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 AMRated: 2

Baader 2" ClickLock Diagonal Mirror
Hey! I wonder whether it'll work well with Skywatcher 72ED?
Answer rated: 1It seems that this telescope has a little problem with eye pieces of short focus lenghtes that the focuser cannot travell deep enough (in-focus).
Obviously SkyWatcher is aware of this problem, the tube of the newer models are 10mm shorter.
Okay, about our star diagonal you can find here more information according the lengthes:

Maybe you can turn in the focuser fully and picture the moon on a white sheet of paper (without eye piece/ star diagonal) so you´re able to
measure the distance with a ruler to find out the back focus length.Answer by: Baader Web Team (Admin) on Feb 26, 2021 9:59:00 AM
