12:33 PM. Tried to tighten the Fastar in the secondary of the N11. I was worried this would happen. I simply could not torque the outside element without turning the inside piece. As per a web article, it would require removing the corrector plate.
Once out, I saw that it could use a cleaning... Found our kit in the work room. Cleaned it in the kitchen.
1:39. Put the corrector back in. Uh oh. I was not 100% sure about the orientation of the corrector glass. I put the etched serial number opposite focuser. That seemed right. I was fairly sure that's where it was when it came out.
2:01. Tried Dietmar's cheshire thing, to do some daytime alignment. But it was no good. The thing flopped around in the mount. I will have to do a star test... And the weather was not looking good...

The index mark on the corrector, and the indentation in the Fastar/secondary threaded ring should both be at 3 o'clock when looking in from the front end, I think, if it has the same standards as other Celestrons I've worked with.
And 3 o'clock is opposite the focuser. I'll test the collimation tonight!
