Description

I took videos before and after collimation - the telescope was slightly out of tune, having not been collimated for a week or so - and was surprised by the improvement. Jupiter was slightly higher in the post collimation image, but seeing was pretty constant. The scope had been cooling for an hour before the pre-collimation image.

The collimation in my 8SE seems fairly stable but I do have to carry it outside to work rather than leaving it in one spot.
