Mark V Großfeld (Giant)-Binocular
I am considering a Mark V baader on a TV-85.
If Glasspath the aperture is 25 mm what is the point of having a Mark V with 30mm prisms ?
Thank you for your reply
Answer rated: 0Sorry - you will need to see this for yourself. Vignetting is not a problem if you put the baffle into the right place. Vignetting must go above 40% until the human eye will see it at the edge of field.
Many eyepiece makers use this effect to "virtually sharpen" the stars at the edge of field - and this never got noticed.
Fact is - you may have a light cone of 26mm entering the bino, but what you actually see is the field created by the 30 mm prisms in the bino.
Please - check the Cloudy Nights forum for Binocular Viewers. You will find hundreds of threads covering this subject. And you will see that all people there regard our Mark V the best.Answer by: Baader Web Team (Admin) on Oct 21, 2021 3:47:00 PMRated: -1

Baader 6.5nm Narrowband Filter-Set – CMOS-optimized (H-alpha / O-III / S-II)
I am looking to buy narrow band filters to image nebulas. I am using the Skywatcher Newton Telescope OTA N 200/1000 DS f/5 in combination with either the Canon Ra camera or ZWO ASI 183 CMOS.
I prefer using the 2inch screw filters.
Is this the right filterset to go with or would you

2" BDS-NT Baader Diamond Steeltrack® Focuser
I want to mount this focuser on a flat (wood) square tube and need to determine the diameter of the hole to make and how much margin for error I have. It seems that I need a hole that is slightly larger than the draw tube, but most commercial scopes have a larger hole. Also, I want to drill the proper holes for the bolts. Please advise.

Baader OTP 60W Outdoor Telescope Power Switching Power Supply
I have a Skywatcher AZ-EQ6, that requires a 11~16V 4A power supply, with a GX12-2 DC Jack (that is very difficult to find!)
Would this Baader power supply work if I were to purchase an adapter cable like this one? https://www.firstlightoptics.com/astronomy-cables-leads-accessories/lynx-astro-silicone-power-cable-21mm-dc-socket-to-gx12-2-dc-jack.html
Answer rated: -1Skywatcher uses stepper-motors that are an easy (almost primitive) solution compared to encoder controlled DC-drive-motors at Celestron-mounts.
One of the downsides of the stepper-motor is the very high power peak requirement during starting up mount motion. Our power supply products are not meant to handle this kind of peaks.Answer by: Baader Web Team (Admin) on Oct 19, 2021 7:20:00 AM
