After I finally got the new wedge aligned, well sort of I took this series of shots.
7 x 2mins
ISO 800
stacked in registax
processed in Photo shop
apply true unsharp mask
mild noise reduction in Noiseware
Pretty happy with the shot, no appreciable drift of guide star for at least 4 minutes. Now need to get it to 10 minutes if I can. Need to do some balancing to scope with a 2 D balance design.
Anyway what do you think?
BTW these shots were all unguided.
