This is an accidental 3 panel mosaic. I started shooting the centre panel and noticed that the camera was 90 degrees away from the ideal framing. Instead of going outside and turning the camera, I thought I would just add a panel above and below the centre. Wouldn't it just be like processing 3 shots?

No, it was much harder than that, and really stretched my processing abilities. I overdid it a bit on the sharpening / blurring transitions. I also still struggle with the medium-bright nebulosity - it always seems to turn out grainy.

I learned some absolutely wonderful Pixinsight scripts dealing specifically with mosaics. MosaicByCoordinates, dnaLinearFit, and GradientMergeMosaic. They made the job a lot easier, but it was still a huge task. Because I drizzled all frames, uncropped mosaics turned out to be 10,233 x 18,614 pixels. Also, I did not notice at first that GradientMergeMosaic saves your image as a 64 bit image. Individual mosaic files were each 4.5GB !

This is my 3rd iteration. It still has flaws if you get too close, but it is good enough I think ! ; )

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.
