Weather is still #@%*##!!! so I'm still fiddling. Managed some sky time on Monday night for a bit of testing through cloud gaps.
Discovered I'd put the TEC element in backwards (DOH!!) so it was warming the camera. Scratch that test for the evening.

Ran some longer exposures in avi on 47Tuc, 8 secs per frame. Gave me some video to stack which was interesting despite the poor seeing. But camera definitely needs the Peltier going as noise really gets obvious otherwise. TEC is now fixed.

The Beam splitter idea introduces too much aberation and reduces light to the guider so that is now gone. 45* Diag in place instead to get focal length correct and the Toucam is so light I don't see any flexure issues. All cables are supported at the mount head and top mounting plate so very little strain on the optical train.

Weather is looking hopeful for later this week although the moon is not !
