This image is made of two seperate panels roughly overlapping in the middle by about 20%. The overlap is important as it allows the software I use to identify the join by overlapping common points it can see in the image, in this case the stars down the centre vertical axis. The two panels where capture on the same night of the 10th of November 2023. The first 'panel' was capture prior to midnight and panel two after midnight. This was done to try and avoid big discrepancies in the background light polution and also to try and give similar amounts of exposure time to each panel, that said Panel 1 is 47 images of 5 minutes each and Panel 2 is 60 images of 5 minutes each. I used my Optolong L-Enhance filter for all the images. Processing of each Panel is performed separately in terms. of pre-processing, the key is at the initial stretching phase when coming out of linear mode to make the two histograms peak around the same point, this way you are limiting any steps in gradient when it comes to the 'stitching' process. I use an old Microsoft piece of software called Image Composite Editor, apparently this is no longer supported and was developed as a research project from Microsoft to allow users to create panoramas from multiple photos. After using this software you are presented with a single image which I saved off as Tiff and then completed my processing in Photoshop.

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.
