M31, an all time favorite

clouds continue over northern Germany (last observing run was for the great conjunction on Dec 21), so can only work on existing data. Tried to combine two sessions of late October/early November, tried to work out the faint outskirts of M31/M32 which clearly are in the data but SNR probably not high enough - thus fighting chrominance noise...

Description: some revisions in my workflow, in particular to get somewhat smoother colors being less aggressive with saturation and better masking of faint areas

Description: reprocessed M31 using the the new General Hyperbolic stretch script (see https://www.astrobin.com/forum/c/astrophotography/deep-sky-processing-techniques/how-to-improve-your-astro-images/). It is very useful to broaden the stretch and working out fainter outer areas of the disk

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.
