Collimation Problem
is there anyone who lives near me with a good understanding of collimation procedures that may be willing to come around and try to sort a problem l am having?
l have an f/5 newt that l am having trouble with, l am collimating with a Howie Glatter laser collimator, l can get perfect alignment according to the instructions but still have elongated stars, tweak the primary and the elongation gets better but by no means perfect, and this is with a Baader MPCC.
when the primary is tweaked this obviously throws out the laser but the stars get better so that is the puzzle, could anyone spare some time to give me a hand with this problem. thanks.
