Sharpless 112 (SH2-112) is an emission nebula in Cygnus at distance of 5500 light years.
The capture was made in the last 3 nights, with a total exposure of 11 hours and 10 minutes. This is my first tricolor narrowband image, Hubble palette (SHO).
Frames : 33x10m Ha (7nm), 20x10m OIII (8.5nm) and 15x10m SII (8nm). Of course, more frames would have been needed for SII and OIII, due to the much weaker signal than Ha, but the nights are short now, getting hotter and wetter, and there is the Moon problem, too (pictures come out with low SNR ).
In addition, I thought of using the Ha image as the luminance.
Setup: Atik314L +, newton SW 150/750, MPCC, Baader filters
Excellent job Marius. There are plenty of objects in Cygnus that lend themselves to the SHO Palette, keep them coming.

Very nice, Marius. Even if it was the tenth time for using your "tri-color narrowband Hubble palette imaging," it's an excellent capture in my opinion. I'm not familiar with this type of imaging. The texture and colors are very striking.

Nice one Marius. Excellent work - and on your first tricolor NB - congrats.
