Well...the jury brain cells are still out deliberating.
Broke the three-arm plastic cover over the collimation screws. It...would...not...budge...unitl it twisted off. I think the central screw that it is supposed to spin on was either too tight, or some of the thread glue on the screw got loose and made it stick. It didn't take a lot for it to break, but I did take the secondary out while trying to get it to move so I wouldn't spin the holder in the corrector plate or the plate itself. It was that stuck. Yes, I was turning it the right direction. The plastic may have been crushed by the screw being over-tightened. It mostly just makes the secondary mirror difficult to remove. It was the handle.
The secondary mirror is hard to remove/install. It's a way tighter fit than my Edge 8 secondary and now has no handle.
The little set/grub screw that indexes the secondary cell in the holder is crazy short and was loose and was barely sticking out into the slot in the holder. You could almost put the secondary in rotated the wrong way. I'll try and get a longer one. The threaded hole is quite deep.
It needed to be collimated. Not surprising, except I don't know how the collimation screws ever jiggled loose from their factory setting. They are very difficult to turn and I was close to wiping out the Phillips slots on one of them. No, I wasn't trying to tighten them past all of the way tight. I'll replace them with hex head screws. Bob's Knobs won't do much good since I can't adjust and look through this scope at the same time.
The collimation doughnut initially had a spike in it, but that went away after fiddling a bit, or with time. I don't know which (I was a bit miffed at the non-spinning cover breaking off) but one out of focus direction there were rings, but the other way was just a quivering blob. Could have been just temperature, but the scope spent all afternoon in my office at 70F, set up at about 68F, and then was taken down a couple hours later at 64F, so not a lot of delta T there. The seeing wasn't great, but not real bad. Maybe it just has to be a lot better.
All of the screws on the thing are very tight/glued in place. That made putting a Vixen bar on the top and installing a finder bracket a small adventure.
M31 looked quite a bit "larger" than I'm used to, but nothing else was really too impressive. Mars. Saturn. Other random things. Didn't get to try the Luminos 23mm eyepiece. There's a little bit of focuser mirror shift. You'd think after 40 years...
I'll be able to get out again this evening, or maybe I'll just work over the secondary cell and replace the screws to get it more easily adjustable. Wouldn't want the screw driver to slip off of one of the Phillips screws and poke a hole in the corrector! I may be able to figure out how to repair that plastic bit somehow. It's not a normal repair part. I'm waiting to hear from Celestron. They better not make me buy a 3D printer!
It's always something.
