Description

I really tried to get this one right. 16 hours of imaging and at least the same time editing since I'm not too good with RGB data (mostly working with NB data from Bortle 9 city).
My main problem was to get  the IFN and pretty bright nebula to show up at the same time. This is probably a ~20% crop from the original picture because I wasn't too happy with the full pic, I need more data for that.

I had guiding problems with a sloppy footing of my mount that I figured out too late and several other small issues that caused problems for post processing (that I couldn't fully solve), but still I'm pretty happy with the result so I thought it's worth a share. Thanks!
