M31 Andromeda Galaxy

Second iteration this year in terms of inaging this galaxy, with additional data captured for longer exposures this past weekend. It's still not as clear as I'd like it so it maybe needs even more data, or something. I'm changing my scope configuration soon so this will have to do for now.

This galaxy looks very similar to how our own Milky Way galaxy would look from the same distance, which is about 2.5 million light years away. Actually, this galaxy is naked-eye visible from darker skies, and if the human eye could detect it completely, it would appear 5-6 moon-lengths in size! Another interesting tidbit is that this galaxy is on a collision course with the Milky Way, expected to “touch” in about 4.5 billion years from now!

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.
