The image consists of 78 180 second lights, darks that are a little too warm to be a perfect match, flats and flat darks calibrated in
Am I the only one who gets all this "glow" around the galaxy? I would love to speculate that it is

Thanks, Joe, maybe that is the case. It'll be interesting to see what more integration time does for it.BABOafrica wrote: ↑Sat Sep 26, 2020 2:18 pm
I'm no expert on the topic, but AFAIK, the galaxy does extend out in the direction of that "glow". You had quite a bit of time with 3min subs. Maybe that is what you are picking up -- the faint edges of the galaxy.

Thanks, John. It is the start of the run that is questionable for me, as at 30° altitude M33 is coming out of the Hartford sky glow. I don't have a lot of tracking trouble at the zenith or after the flip. I haven't noticed the same type of issue with M31, which also starts out in the Hartford lights.JohnP_1 wrote: ↑Sat Sep 26, 2020 7:07 pm Nice image Bob. M33 is a beauty, yet tricky to capture and process. As far as the glow, it is hard to say. This target is almost directly overhead for our latitude, which has its drawbacks. When I image even a little east of the zenith, I get a lot of sky glow from light pollution sources. I'm not sure you can pull in the IFN with 3 minute subs. The SNR goes way down with 4 hours of data, but, the signal does not itself increase.
