M33 The Triangulum Galaxy in HaLRGB

With a diameter of about 60,000 light-years and including around 40 billion stars, the Triangulum galaxy (M33 or NGC 598) is the third largest member of the Local Group of galaxies. It is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum.

This is my second capture of this beautiful spiral galaxy - last year's effort was one of my first with my mono camera...hopefully a year on, some improvement can be seen in terms of capture skill and processing!

Captured with APT, pre-processed with APP and post-processed with Pixinsight. This is a heavy crop of the original image, which I will look to include as an intermediate image.

Thank you for looking!

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.
