M31 Andromeda Galaxy revisited with Hyperstar

Revision title: iPhoto postproces

Annual revisit of the Andromeda galaxy with better processing understanding - and the incredible resolution of an EdgeHD 11" combined with a Hyperstar field of view.

Stars taken with UVIR image, galaxy with L-Enhance dual band OH.

Pixinsight Process
- new Fast Batch Processing script
- HDRcomposition of 10s and 180s L-Enhance OH dual band iamges
- OH and UVIR subs cropped and horizonatlly flipped
- AutoLinearFit of subchannel to same mean
- color calibration SPCC with background neutralisation
- GraXpert gradient removal
- BlurXterminator sharpening
- Graxpert Denoise
- StarXterminator seperation of stars from UVIR image
- STF 0.15x intensity stretch with HistoTrafo
- HDRMultiTransform
- color saturation and contrast with CurvesTrafo
- Pixelmath unblend integration of UVIR stars

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.
