Andromeda Galaxy M31

This my modest contribution to image this beautiful galaxy lying just “next” to us. I decided to give a try on this target during two nights with fair seeing and transparency, under darker site in the Jura Mountain. Messier 31 is one of my absolutely-to-do-image-in-a-life as Orion Nebula, LMC/SMC or Pleiades are.

It’s always a pleasure to achieve such an imaging session with a good result (at least to my eyes 😉) after hours of postprocessing, dealing with Pixinsight’s parameters and fine adjustments. I’m still learning it…

So, what could I say more about this famous neighbor than already explained by many other astrophotographers here? About 2.5 million light-years away from us, M31 is home of one trillion stars, according to last Spitzer’s observation back in 2006. M31 has got two companions (of 14 known) that are easy to identify: M32 and M110.

By the way, I don’t know witch orientation is the true one: I’ve seen pictures of M31 with M110 once above, once under… Well, does it really matter in space ? 😉

Criticism, comment and feedback are welcome.

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.
