overdue for alignment

I wonder if the view in Mom's 6" Newtonian has eroded a little as I've not done any collimation. Not since I did it the first time. Over four years ago!

I've heard that you need to do this regularly for reflectors.

Mom's 'scope has certainly been bounced around and jostled about.


And I shall add another item (collimate) to my observing session "pre-flight" check list.


Maybe that's what was bugging me last night. Maybe that's why I felt my vision was off. Sure, I am suffering another cold. But still, maybe the 'scope is way off and that made it seem less crisp, less contrasty.
