Otherwise known as the PacMan Nebula. This was to see how the new ASI 2600 compared to my old Canon 550D. Really it needs a narrow band filter to do it justice. Both pictures were guided and taken through the 130 PDS mounted on an EQ6-R.
First we have 6 hours and 54 minutes total exposure across 3 nights in October with the Canon 550D. A mixture of 3 and 5 minute subs.

Then we have 2 hours and 54 minutes with the ASI 2600 and all three minute subs
