I didn't think I would get enough data for this galaxy, but I'm going with this image and moving on. It took a little work to keep the nice star field and optimize the galaxy because I did not separate them out during processing. I'm getting about 2 Galaxies a night on my "Galaxy Safari".

HISTORY   1 Stacking method SIGMA CLIP AVERAGE
HISTORY   2 De-mosaic bayer pattern used RGGB
HISTORY   3 Colour conversion: AstroSimple interpolation.
EXPTIME    = 12240 / Total luminance exposure time in seconds.
LUM_EXP    = 360 / Average luminance exposure time.
LUM_CNT    = 34 / Luminance images combined.
LUM_DARK   = 25 / Darks used for luminance.
LUM_FLAT   = 30 / Flats used for luminance.
LUM_BIAS   = 25 / Flat-darks used for luminance.
LUM_TEMP   = -5 / Set temperature used for luminance.

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.
