I acquired the RGB data back in 2012 it was done under a 70% waxing moon so I only did 15 second shots then with the Hyperstar and CPC deluxe and extensive processing time to bring out what data I was able to get. Fast forward to this year I finally got around to getting the HA data last night under a near full moon which greatly helped to enhance the previous data. I captured 40 subs at 120 seconds ISO 1600 and ended up deleting half due to faint clouds moving in & out. This was also with the Hyperstar and EdgeHD 11 guided on the CEM60 mount. The Astronomik HA filter makes weird noisy artifacts in the corners so I cropped it down as my usual flats did not work and made it worse.
