M31 was the first target when I got into this hobby exactly one year ago. Still remember the struggle of finding this target in the Nikon D500 live view window. The first result was just nothing - but at that time, it really made me excited for couple of days.

A year later, I decided to revisit to M31. It does mean a lot to this hobby of mine. Actually it took quite long time for me to collect the data, H-Alpha was captured in the white zone backyard. L/R/G/B was captured at TAS Atoka dark site.

It's also my first attempt to do a HaLRGB. Indeed clueless... Not sure how I made it out.

Clear Skies!

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.
Dismissals 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.
