M 31 (Morocco - Atlas Mountains)

Preview from M 31 image taken during my current astronomy vacation in Marokko. Data collected from the Atlas Mountains (680m), SQM 21.5 ~ 22.1 and seeing below 1 arc second. Perfectly darks skies and excellent seeing. I used a setup from a friend so not everything is optimal like backfocus and sampling, but I cannot complain about these conditions :-). Will re-do this image when I am back in the Netherlands again with a calibrated screen.

11-03-2019 update: final version.

With many thanks to Hans Hoogkamer for providing me with this opportunity in general, providing the material, providing a stay and much more! Also thanks to Janina Martynaityte and her mother for providing the good care during my stay in Maroc. Could not have done this without them!

Description: Made background more black, it was to light. Also cleaned up a bit. Unfortunately it seems I cannot fix the core using PixInsight HDR, I want it a bit more dim but I think my gain setting was to high and that data is just not there to make the core less bright...

Description: Completely reprocessed using AstroPixelProcessor as a test. Must say I am pleasantly surprised by the result! Core is allot better, background better and stars are smaller! Will investigate further...

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.
