M33, The Triangulum Galaxy (Central Region)

Very nearby, diffuse, spiral galaxy. Part of the local group that includes the Milky Way. Lots of active star formation. Well-known object for amateur astronomers.

Almost skipped this object because it's apparent size is much too large to fit in the field of view of my sensor. The image field of view is only of the central region of the galaxy, but I'm glad I took this; lots of interesting detail that wouldn't be resolved in a more distant galaxy. What look like blue stars are really unresolved clusters of young stars.

Captured images over two nights; one night of L exposures, and one night of R,G,B exposures.

The final image used
L - 72 (of 75) frames x 300s @ Gain 100 @ -10C = 6h 00m exposure time
RGB - 26 (of 26) frames x 300s @ Gain 100 @ -10C = 2h 10m exposure time, each
12h 30m total exposure time

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.
