M31 - The Andromeda Galaxy

Here is my version of M31 the Andromeda Galaxy! Andromeda is one of my favorite deep sky objects, I've always found it stunningly beautiful and love that it's close enough to see a lot of detailed structure within the galaxy. I put a TON of time into this one with over 28 hours of total integration time, perhaps a bit of overkill but I wanted to give it my best attempt with my equipment and skies.

The Andromeda Galaxy is a spiral galaxy 2.5 million light years distant and is the largest galaxy in our local group of galaxies. M31 is moving toward the Milky Way and will collide with our home galaxy in roughly 4 billion years. There are some really cool videos out there I'd suggest looking up that show what the night sky will look like as Andromeda gets closer and closer to us. I was surprised to learn that Andromeda is actually a barred spiral galaxy like the Milky Way, you can’t see it in the visual spectrum due to its angle relative to us. Also in the image are two of Andromeda's satellite galaxies, M32 and M110 which orbit the galaxy similar to how the Large and Small Magellanic Clouds orbit the Milky Way. When you zoom into the image you can also see several of Andromeda's estimated 460 globular clusters and a number of red HII star forming regions which popped when I integrated the Ha data into the image.

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.
