Cleaned the C-14's corrector plate and spent a couple of hours on collimation and thought I'd try a couple of pictures.
Both of the following are made from stacking 30 two minute exposures, each which was first dark subtracted and flat fielded.
Scope was working at its native f/11 (3,910 mm).
Camera was binned 2x2 resulting in a scale of 0.733"/pixel. Maybe next time I'll try 1x1 (0.366"/pixel).

I'm happy with the collimation and guiding but I just can't get the tiny pinpoint stars I see in so many others' pictures. Grumble...
When I try this again I think I may refocus after every 5 or so images as the focus did change slightly during the time it took to shoot all 30 pictures.
BTW, if anyone is interested I kept all of the original data which I'd be happy to email out in case someone else can do their magic (Photoshop) to make the stars smaller.
Carpe Noctem!
