Another year, another M31! I got a pretty good result last year in pretty bad sky conditions. This year, I was back in my Bortle 7 backyard (Bortle 8 last year) and the moon was almost non-existent this time around...in theory superior conditions.

Something new I tried for this image was to drop the gain values for my broadband filters from their usual values and increase sub length to 60 seconds instead of the usual 30 seconds...idea was to increase dynamic range and also lower the number of subs on my hard drive!

Intriguingly, I now have decent data on M31 over the last three years...it might be worth combining them all for a definitive image...hmm...

...thanks for looking!

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.
