I'm still figuring things out but seem to be having issues with maybe my camera gain setting (ZWO ASI183MM pro) or perhaps it's just my not knowing how to properly process the data in PixInsight. I'm getting tons of amp glow (mostly cropped out of this final image). I first analyzed it traditional way using all the calibration frames (bias, dark, flat) with mostly the default settings in PI and that gives me amp glow but also seems to preserve the main extent of the image away from the amp glow. I then reanalyzed *without* dark optimization during the dark frame calibration step, and this removed the amp glow but also got rid of a lot of the signal in the light frames, especially Ha which was pretty much destroyed and super grainy. It also created some really bad square-grid artifact in the red channel after the image registration (StarAlignment) step that could be removed by using bilinear interpolation rather than the standard "auto" interpolation setting that is default. However, at the end I decided just to go back to the original processing method and accept the amp glow despite how bad it was. I'm sure there's more troubleshooting that could be done, but I'm wondering if the better solution might just be to move on to a better camera without the amp glow (e.g. ZWO ASI1600, which I probably should have obtained instead of the ASI183 in the first place...).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
