Hi I'm here for the first time, but not all that new to astronomy. I do however have a request if anybody can assist me with advice on a 200mm f4 (I was suprised to find my scope on Brian Nolan's first telescope report).

I like the scope and find it great for the deep sky objects but I went to replace the focuser and found all manner of headaches from the focuser too short in depth (I had a 15mm spacer made up for it), to the collmination way out.

When the collmination is in alignment the star patterns resemble misguided fireworks and the field is in focus on one side and progressively fades out of focus to the other side. Does anybody have any ideas?
