Mountains of the Seagull, a 200-megapixel mosaic

Revision title: The mountain range under the elbow

Hello!

During the last couple of months I have been imaging the Seagull Nebula region, a large emission nebula on the edge between Canis Major and Monoceros. The vast size of the nebula required assembling a 4-panel mosaic, the new Target Scheduler plugin for NINA made the acquisition a breeze.

The image is built from SHO exposures for the nebula (roughly 2:2:2 hours per panel), augmented with RGB for the stars and some additional colour punch (roughly 40:40:40 minutes per panel).

Please see the revisions for the full view of the nebula and selected more detailed crops from the 200-megapixel original.

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.
