M33 - Triangulum Galaxy

My first long-exposure 2 hour (n=25 x 5 min, 0% Gain & Offset) live-stack from last night in SharpCap 3.1 using my Altair Astro Imaging & Visual Astronomy 178C Hypercam through a TS f260mm f/4.3 doublet with live dark subtraction (n=7).

This is the Spiral Triangulum Galaxy -

M33 and it's only 3 million light years away with a 66 million light year diameter (compared to our Milky Way, which has a diameter of 100mly) and contains an estimated 40 billion suns, about a 1/10th of that in the Milky Way. It is believed that this Galaxy is gravitationally bound and interacting with the closer Andromeda Galaxy and it contains the largest Stellar Mass Black Hole ever recorded.

There is a dust mote in the capture, so I need to start doing live flats calibration too! Processed very lightly in Pixinsight.

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.
