A good day to be in the shop, trying to figure out the collimation problems with my telescope. Looks like not just a mirror alignment problem, it has focuser tilt too :(

That's one thing I do like about my refractor... no collimation with it... but it can suffer focuser tilt. I noticed some "blurring" on some photos and after checking everything I found that the mount screws for the focuser tube into the scope were slightly loose. causing left/right play in the tube. Tightened them up (after putting some blue LocTite on them) and no more issues so far.
I have a NexStar 8se that I know I will have to eventually collimate, but I made sure I made it easier by getting some "Bob's Knobs" for it.
I've been debating either getting rid of the NexStar and getting a refractor (using the money from it to get a better one) or simply buying an intermediate priced refractor to play with. I like how the SCT does for planetary... it really pulls in the planets well.

Ya better hurry and purchase it, China may not be shipping to your country soon.
