I am trying to fix the tilt in my system (I have another thread going on about this) and someone said I should check the focuser is aligned with the main axis.
How exactly do I do this? It looks aligned to me but is there a precise method to make sure the focuser is aligned before I start making adjustments to the tilt adjuster?
I have a Meade 70mm f/5 petzval. I did install a Riegel Nstep auto focuser and when I installed the bracket that holds the motor, I had to remove two small screws in the focuser which were replaced with a couple of larger screws in their place (please see image below). I am not sure if this could cause the focuser to fall out of alignment...
Thanks a lot!
