My 1.8x glass path corrector appears out of collimation on f/5 while the 1.7x works perfectly.
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?

Is it possible to stack GPC's without losing image quality?
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.

Hello. I'd like to use this corrector with William Optics binocular. I need some additional T2 connector between the corrector and bino. Is there a way to make it work?
Greetings

Hi
Could I use this with my Skywatcher MN190 Mak-Newt, which is 1000mm f/5.2?
I’m looking for a “Barlow” effect of between 1.5x-1.8x but am struggling to find one.
The MN190 is already well corrected, would this adaptor introduce unwanted aberration?
Thanks
Jeremy
