M31 (my first mosaic)

Revision title: Now, with more data!

With only 2 hours available last night, I thought it would be a good idea to take something bright and big and turn it into a mosaic. My Z73 can barely squeeze M31 in one frame so I went for two frames of around 50 minutes each. First time doing a multi panel, and first time NINA went through a meridian flip. I was only a bit nervous... In the end I had to ditch 5 out of 28 (120 sec) frames from the first panel and 2 out of 24 from the second panel, mainly due to satellites and a bit of cloud. And Clear Outside was spot on with its prediction, as clouds started to move in exactly after two hours.

Stitching everything together in APP is on the one hand pretty straightforward, on the other hand there a lot of parameters you can/should play with, and the differences are very subtle. All in all I am very happy for a first time and given the limited time I had. The only thing that was a bit disappointing was that PHD2 did not want to go below 1" and kept hovering around my scope/camera resolution. I got 'Star lost' a couple of times, but the Patriot Astro sequence made sure everything kept going until the end.

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.
