M31 - Andromeda Galaxy

Andromeda is ~2.5 million ly distant and is moving toward the Milky Way at 250,000 mph. In a few billion years there's going to be a *big* collision. Andromeda is much larger, but neither galaxy will survive intact. Andromeda's diameter is 220,000 ly with a trillion stars and has an angular size six times greater than the full moon. The bright core is the result of millions of stars crowded together, orbiting a supermassive black hole at near-relativistic velocities.

This is my second attempt at this target, now with a little more experience under my belt.

I'm slowly accepting that from my location I need longer exposures if I want good images. This one used 11-minute subs, but I can go longer. Just need the weather to cooperate. I'm still rock bottom basic at processing.

I'm new enough at this that I'm totally amazed that this little 2.56" telescope can capture this incredible galaxy.

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.
