This is a combination of data, some that I previously put up here (my RGB and Francois Theriault's Ha, see and new Ha data from Ole Alexander Ødegård. The new data was particularly good for fixing the stars. Altogether nearly 7 hours. RGB with a 5" apo refractor (and Canon 60Da) and Ha from two Newtoneans (8" and 12" with an SBIG ST8300M and a mono modded Canon 6D, respectively). So a mix of data from Sweden, Canada and Norway.
Thank you Francois and Ole!
