Andromeda in LHaRGB

M31, the Andromeda Galaxy along with the sister galaxies M32 and M110. This is my most recent attempt at imaging this behemoth. It is located roughly 2.5 million light years from Earth, making it part of the local group of galaxies that contains the Milky Way. I used some Ha data to bring visibility to the nebula within the spiral arms. Each of the red regions seen along the outer edges are these star forming regions. All together there is roughly 26 hours of data used to create this image.

I really like pictures of galaxies. There is something surreal about looking at a structure that is hundreds of thousands of light-years in diameter, containing nearly 1 trillion stars. For me it really starts to put the sheer scope of the universe into perspective. It is impossible to look at this galaxy, one of literally billions of galaxies in existence, and not think that there isn't some intelligent species staring back at our Milky Way and wondering if we exist.

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.
