M31

Yes, I can hear it...
not another Andromeda please!

Indeed it's not another, but it's (all) my previous M31 in a single image.
I made this image to train the skill of the post processing collaboration of multiple setup.

This M31 was shot with:
- Meade 5000 80 / 480 (2015);
- TS Flatfield 65 Apo (2017);
- Gso 10" f/3.8 (2019).

The total integration time is more than 50 hours.
I found out that integration time is less important than to have good data; those raw were acquired long time ago, when I was at the beginning; so now I could not make the miracle coming out with a super image. The 2019 data were ok but the problem were the others.

Anyway the final result seems not too bad, knowing how not good were the data, shot with a reflex.
I had fun in this multiple setup image, something different this time for me.
Thanks for watching.

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.
