Messier 78 - A nebula I thoroughly enjoyed finishing. As in never processing again lol. I love this Nebula but because my RGB data was so bad due to bad flats and darks, it made this image really hard to process...I pushed through though.
This nebula is a beautiful reflection nebula amidst the vast hydrogen clouds of Orion. I gathered 16hrs of Lum data and 2hrs each of RGB. If I grabbed more RGB data I could really stretch the colors a tad more but overall, I’m relative happy with this one.
I tried this one recently and got pretty beat up. You really did a great job pulling out this nebula’ beauty.

It sure is a fine image Teagan!

Thank you! This could have honestly used 5 hrs of RGB each channel. Im surprised that at fé3.9 this was still a challenge. I dont even want to think about trying this with my f/8 RC!
I've never been able to capture a good image of this target. You have captured some wonderful internal details of this area along with the colors. Well done indeed.

I've tried at least three times to get something reasonable with imaging M78. This is beautiful. Well done! One question: gain of 0 with the ASI1600? I don't know anyone that sets 0 as gain. Is that really what you used?

I Have been using gain 0 actually! My buddy and I did some testing and found the noise to be lower at gain 0 over 139 for luminance. I got some banding in my RGB channels which can happen at such low gains. I’m going to move to gain 75 and what I think. I do like shooting at unity though especially for narrowband.

Interesting. For my LRGB I use unity most of the time (139/21) and for NB 200/50. However, the native drivers for the ASI1600 are no longer supported by SGP. Don't know if you use SGP, but they (and ZWO) recommend using the ASCOM driver. However, you lose the capability of setting Gain and Offset on a per event basis - only Gain. So I'm trying to determine what Offset to use for all gain settings.
