Thanks for that, Got scope colimated to a point with out a centre dot and has improved image a bit but still suspect pinched mirror - read the article on this, thanks for that. needed to put dot on mirror anyway. The Corrector is definatly glass as I removed it to check the centering of the secondary in the focus tube with and with out it - wish I read about the white paper trick before I did this
Still getting triangle star colimation test which suggest pinched mirror, there are three main mirror mounting brackets!
(I checked my eyes and are ok.)
Paid $280.00 brand new with EQ3 Mount?
If I get any more probs after fixing pinched mirror, spotting mirror, and re-collimating I will start a new thread. I have a laser colimator arriving in a day or two which will help a bit.
Thanks again
