I think just about everyone who tries to process M33 has a real challenge ahead of them, and this time was no exception. One thing working against me on this image was the moon. It was waxing crescent over the 3 days when I shot this, and when I started my processing, there was a horrible red cast on one half of the image and blue/purple cast on the other half! And of course M33 is so faint that its only natural to stretch it as much as you can so you get those faint spiral arms. Well, doing that I ended up stretching those horrible red/blue casts even further. You can still see some of the remnants around the top half of the galactic arms. But on a more positive note, the noise was not bad on this image and it was pretty easy to remove. HDR was also easy to do, and I was able to pull out a lot of contrast in the core.

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.
