Just for a laugh, 4 minutes of data of M57 Ring Nebula with Canon 7D

[FaB-Bo-Peep]

So a friend has upgraded his DSLR and I'm trying out his old Canon 7D, (18MP), which should offer a significant upgrade over my current Rebel XS, (1000D), 10MP. 

However between the clouds, struggling to set the 7D up in the same way as my XS, and the very limited hours of any kind of darkness, I made lots of progress in terms of setting things up but achieved very little in terms of usable frames.

This image, (and the cropped version), are the result of just 4 minutes worth of data, yes you read that right, 4 minutes! (2 x 1 minute and 1 x 2 minute exposure), which I stacked just for a laugh as a memory of the evening. By the time I took them it was getting light so the fact that anything is visible at all is most encouraging for the next test session with the 7D which will hopefully be under less challenging conditions.

Skywatcher ED72, OVL field flattener, Optolong L-Pro filter on an EQ6-GT, all controlled from my ASI AIR Pro. Image stacked in DSS and processed, (with my very limited knowledge), In StarTools.
