Good morning guys, any suggestion for sensor tilt correction?? Will you need a tilt plate or adjustments to the focuser? I did the test yesterday with the Reflector CF 200mm f5 Coletti optics and Dony de Castro mechanics (curved spider secondary mirror). There were 1 frame, the tilt of the sensor is noticeable, the coma corrector didn't handle it (the distance was the best I could get by testing the focus at the 83mm ends).

Two suggestions:
1) Download ASTAP and use it to analyze the tilt quantitatively. If you're using NINA, Frank (of Metaguide fame) has worked on a plug-in for the same purpose.

2) I do not own one, but everything I've read about the Gerd Neuman tilt corrector has been positive, and it's a beautiful design. I have a bespoke TC for my Astro-Tech, or I would get a GN one. https://www.gerdneum...lting-unit.html

Thanks fewayne, I'll follow both suggestions and do new tests.
