Description

This is a combination of data, some that I previously put up here (my RGB and Francois Theriault's Ha, see http://www.astrobin.com/242439/B) 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!
