Hi all,
I am seriously tearing my hair out on this one. Set up the scope to take some quick shots of the moon tonight and for some unknown reason it seems like my focal plane has moved considerably. I have not used the scope for about two and a half weeks but nothing has changed or is different in my setup. I use a Bintel 10" F/4 imaging newtonian with the standard 2" crayford focuser. I attach a DSLR camera and multi purpose coma corrector. The focal point of the setup used to be well within the range of the focuser but now I can not acheive focus.
It just starts to get focus when I run out of travel in the focuser (all the way out).
Is there anything that anyone can think off that might have happened since I last used the scope? The sledgehammer in the corner of the shed is starting to look tempting.
Cheers
Greg
