Dear friends thanks for looking, my scope is a classic 10 inch f6.3. I have to be very careful and tighten the mirror flop screw adequately after collimation or the flop wold result in severely off collimated / coma error. The qhy 10 just arrived for full moon-)

Yup make to tighten the screw, you might even notice movement when focusing. due to moving the mirror.
