Description

M51 (again). I had some calm nights and it really helped the tracking. With the CEM60 I was getting around 0.6" RMS error.

I was intrigued by the faint 'dust' (actually star I am sure) lanes at the right of the picture. I tried completing the arch, but couldn't quite do it. In very dark skies I tried 900 second exposures to improve the SNR.
