M33 - Triangulum Galaxy in HαRGB

And the winner is ... PI. This was quite a journey to get a decent image of M33. I took those images quite a while ago, and I tried to get something out of it with PS, but to no result that I could "live" with. All RGB images from my backyard suffer from severe gradients due to hard light pollution from the east. Only PI was able to really resolve those issues. And PI did an excellent job to integrate the Hα data with the red channel, by far superior to PS. BUT ... PS was not completely out of the picture, I still like the final adjustments in PS, they are so much easier to handle, but maybe this is just because I am more used to PS. At least I learned now how to create an HαRGB with PI, that was good. There are so many options to deal with in PI that it almost suffocates you. I wish I could learn everything at the same time, but this is indeed impossible.

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.
