M33 (NGC0589) Triangulum Galaxy

This is M33 the Triangulum Galaxy. It is the third largest galaxy in our local group (preceded by the Milky Way and the Andromeda Galaxy). It appears to have been discovered before 1700 which amazes me (I can't believe how good astronomers had to be back then in order to identify objects such as this one). It is 2.73 million light years from Earth and has a diameter of 60,000 light years.

I really like the prominent HII regions visible near the core and in the outer arms as well as the OIII regions at the outskirts.

This one was an interesting one for me. I had to throw away quite a few subs due to erratic camera behavior (to this day I haven't been able to reproduce the issues I was having). I also tried a different post processing technique; I extracted the luminance layer towards the beginning and processed it separately all the way through before recombining it with my RGB image at the end (credit goes to my friend and colleague Jeff who got me thinking about how to do this).

I think those who say to process luminance separately are definitely on to something as the detail I was able to bring out in that layer on this one was higher than normal.

Let me know what you think!

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.
