A target I first attempted back in 2013 with the same telescope & mount, but back then I used a Canon 500D DSLR and only imaged in Ha.

Now I wanted to improve on that and make a colour version. This is all new data taken in June and July 2018 over 20 nights.

This is one of those rare images that I have not displayed with North at the top, North is to the right and top is East.
