Galaxy Triangulum M33

What a difference a dark-sky site makes! Taken from Weybourne in North Norfolk UK during a Moonless cloudless night with Edge HD 8 and focal reducer on an AVX, ZWOASI2600 MC Pro, Optolong l-Pro broadband filter, guided with Lacerta.
The Triangulum Galaxy (M33) is a spiral galaxy 2.73 million ly from Earth in the constellation Triangulum. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. The galaxy is the smallest spiral galaxy in the Local Group, just 60% of the size Milky Way with 10% of the number of stars (40 billion). It is believed to be a satellite of the Andromeda Galaxy or on its rebound into the latter due to their interactions. It also has an H II nucleus.

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.
