M33 - Triangulum Galaxy

I'm pleased with this image given that the first subframe was smeared badly due to tracking errors caused by cloud. That cleared and stayed away until 5 minutes after the last frame that I took. I'm delighted with the detail that captured, especially that of NGC604.

M33 is a spiral galaxy approximately 3Mly from Earth and is part of our local group of galaxies. It is believed that it is a satellite galaxy of M31 (the Andromeda Galaxy) due to their gravitational interactions. NGC604 and NGC595 are large H II regions in the galaxy and are highly active. NGC604 is approximately 1500 light years across, over 40 times larger than the Orion Nebula and over 6300 times more luminous.

Description: Re-processed the same data with Pixinsight 1.8. It has picked up a lot more detail and part of a spiral arm that I could not see before. I thought I had the edge of M33 but in reality its filling the frame! I have checked with other images and it is correct and not just poor processing. I'm rapidly becoming a big fan of PI.

Description: Adjusted curves to bring out the outer spiral arms more and brighten the image a little, also added a bit of warmth to the core of the galaxy via a small change to the blue/yellow curve adjustment.

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.
