A Slice of Swan - 3-panel mosaic in Cygnus

Here's a 3-panel mosaic of some of the emission nebulae in Cygnus spanning NGC 7000 to SH2-115. This was shot with two different dual-narrowband filters, Ha/OIII and SII/Hb. In this case, I used SHbO for the RGB mapping and Ha as a luminance layer. Turns out there's not much H-beta in SH2-115... but it did make for an interesting blue/red/purple composition.

This was a total of about 55 hours integration time divided about evenly between the three panels and two filters. Processed in PixInsight with the stitching done in APP, and final processing again in PixInsight.

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.
