Thanks for that compliment. Yes the gear is very good and deserves close maintenance and optimisation.

I think I'll add to it. Its quite a bright galaxy so its not taking too long to build up a decent signal.

If I stretch your image and do a tiny bit of wavelet smoothing, I see quite a bit more of the faint outer spiral arm toward 4 o'clock. It's a great image already, but if you clipped the blacks a bit less I reckon you'd bring out even more.
Good work with the collimation. It looks perfect. The collimation screws on our CDK are 3.5 metres above the ground, and it's pretty scary up there in the pitch dark!
Best,

I am sure there is a bit more in it but I was already starting to see the effects of not enough exposure so I left it at that point.
My CDK is about 2.3 metres up so a short step ladder wasn't too bad. Lots of getting up and down though - about 40 times!
CCDInspector is good but it assumes the camera is dead square. Also the seeing was poor at times last night then improved after midnight. So not ideal. I got it to about 2 arc seconds error. So pretty close. It was at 7.1 arc seconds error when I started and the stars were round anyway.
Also CCDInspector shows only 3 collimation screws in their graphic. The CDK has 4!
