Thank you.
I will give that a go next clear night. I'll take everything apart and reattach.
I've read online that the field flat 6aiii has to be set at 7.1. Some other sources state otherwise.
So I'll have:
- 1600MM - 6.5mm
- EFW - 20mm
Required back focus is 55mm but need to add 1/3 filter thickness which us 0.67mm.
Total of 55.67mm of back focus so need to make up 29.17mm.
I hope im doing that correctly.
Linking back to my other post. CCD inspector usually has better results than ASTAP then I use Pixinsight to check all corners. What should I be using to check my results?
Thanks!
