This image represents a number of firsts for me. It is my first image from data collected over multiple nights. It is my first attempt at a mosaic image. It is also my first use of AstroPixelProcessor, and I have to say I am very impressed by this software.

APP was able to blend panes together seamlessly, despite large variations in background sky brightness and obvious gradients due to changing moon phase over the time period when the data was captured.

The object itself needs no introduction - M31, The Andromeda Galaxy.

Feedback and CC is very welcome.

EDIT: Lots more data added to the original version which consisted only of 60" exposures. A few 120" exposures, and lots of 180" exposures at the new moon allowed me to pull out a bit more of the outer arms of the galaxy. I think I'm calling this project complete, at least for now.

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.
