Finally one clear night.
The first and last 'guided' image from the 12" reflector.
This required balancing and collimation at the specific attitude.
A total hassle.

This scope has f/5 focal ratio and the FOV is 30' by 40'.
As such could only capture the head.

The mirror is badly corroded so I was happy for anything.

30 of 240sec subs. (120 min)
20 darks, bias and flats
