Hi Glend,
Yes the coma corrector is tricky.
It actually extends the focus point out to allow for more back focus with a Newt . to take the
filter wheel & OAG.
I must have had the focuser fully in with the 40mm extensions
so why did I go for a shorter extension of 20mm?
I think I am confused because the first pictures I took were with
another mirror & no extensions.
The new mirror now - a higher quality one -is a bit thicker.
It would be so easy if I could just move the mirror up & down to any point I wanted.
Changing to new extensions is a major job.
cheers
