Hi everyone
My question is regarding my travel scope which is a skywatcher 80/400 which sits on an alt as mount.
The focuser is just a standard unit and I find that I miss the crayford from my 10" dob. And focussing is a little bit more difficult.
I have noticed that bintel sell crayfords for these scopes and I'm wondering if anyone has replaced the standard focuser with on of these crayfords.
Is it a straight forward fit? Can I do it myself?
Thanks
Peter
