I'm interested....
I'm curious how you managed to calculate how much to take off.
If your digital camera doesn't come into focus because you don't have enough in-focus then how do you measure the amount you need?
Its not like you can get the camera any closer without removing the focuser... even then that may not be enough....
Or were you just estimating?
Cheers
Dave.
PS. My 10" Dob arrived and I can't get focus with my 20D. It seems to get close though....
