M31 My first mosaic

This is my first attempt at creating a mosaic and was more of a proof-of-concept experiment than an attempt to create a high quality image. As it turns out, there are certainly artefacts and issues with it that I will learn to address, but I am very happy with the overall result. First mosaic, only an hour of integration, from my backyard (well, even better--inside nice and warm with my rig outside at -15C!)

4 panels each with 30x120s, MosaicbyCoordinates then GradientMergeMosaic then basic processing, nothing fancy, so basically one hour integration.

Biggest challenge: NINA and I didn't get the overlap/pointing tolerance quite right, so the initial mosaic had a gap. My first try I had the rotation a bit off too, but there was no gap, so I used the data from that one to fill in the gap of the second one. I think I know how to avoid this issue in the future--time will tell!

Description: cleaned up some artefacts, reduced stars a bit more selectively; still not really happy with colour of stars or the galaxy. I'll definitely be back for more and better data--too nice a subject to leave like this!

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.
