Product Questions
I have the following: Baader 2" glass path corrector for refractors, SC and other systems. Extension factor 1.8x.
I have tested it with various diagonals and in 3 high quality refractors with my Mark V Binoviewer.
Everything looks good in my 180mm F7 and 101mm Petzval F5.4 refractors. But in my 140mm Petzval F5 refractor the stars appear out of collimation on regular stars as well as on an artificial star tested indoors. When I replace the 1.8X GPC with the smaller 1.7X GPC or 2.6X GPC everything looks good. The scope has perfect collimation. However, when I use the 1.8X GPC something is out. It doesn't really make sense so I am wondering if you know what might be the problem. Perhaps F5 is too fast for the 1.8X GPC. Is that correct or could it be something else I am overlooking?
For example, a 1,25x or 1,70 GPC on top of the 1,7x newtonian GPC with a Mark V binoviewer. That would give a nice flexibility.
A greeting.
Thanks.
I am wondering if I can use the 1.8x glass path in front of the Baader T2 Zeiss prism + maxbright binoviewer? I see it is just recommended to be used in front of the mirror diagonal, not sure if it will perform worse in prism diagonal?
