Just saw this...
Thanks for this info Glen.
I have had this scope for a while now and never touched the corrector plate or secondary. This scope holds collimation extremely well. Only check alignment every now and then. Still using the standard focusser with a Zwo asi533 color camera. As long as you tighten locking screws properly the focusser works well with pinpoint stars across the field. 1000mm focal length and a great all round scope.. This scope is a keeper.
