Description

My take on NGC 6946 aka the fireworks galaxy.  This one isn't impressive as far as integration time or anything like that, but the journey to get the final image was quite a story.  This image started as a side project when I went to my friend's dark site, and my main target only allowed me to capture for half the night before going behind the trees to the west.  My friend Ron suggested I get some RGB on NGC 6946 for the rest of the night since it would be a nice FOV in my scope and really shines under dark skies, and notoriously hard to get good color on without dark skies due to the Milky Way dust blocking it.  So I ended up collecting 30mins. each RGB, and when I got home and combined it, I was very impressed with how well the colors looked considering only 1.5hrs. of data.  So the next new moon, I was lucky enough to get another Saturday night with clear skies at the dark site, so I decided to collect luminance the entire night.  This would have been the end of it, but I encountered a major problem at the dark site.  The ride up was pretty bumpy, and apparently my tilt plat came loose... the stars looked awful.  I didn't know how to even use the tilt plate, so I was kind of lost in the dark(pun intended).  I ended up using a NINA plugin and messing with the tilt plate to try to fix the issue, but the resulting stack still didn't yield acceptable stars.  Luckily I was still able to use the data though, thanks to a trick Ron mentioned.  I shot a short luminance stack at my parent's bortle 4 driveway the next new moon, after I fixed my tilt issues.  I then stacked the dark site data plus my parent's data, as well as just the data from my parent's house.  After that it was a simple matter of replacing the stars in the full stack with the good stars from my parents.  I thought it was going to be simple anyway... I ended up having an issue with a grid pattern left over in the resulting starless image in the brightest stars via starnet2, which would show up in those stars after star replacement.  Luckily I have an awesome group of friends from the M 106 Megaproject, and Francesco took a look at my raw stacks and managed to fix the problem using starXTerminator.  So this image wouldn't be possible without his and Ron's help.  I hope you enjoy!
