Please view at full resolution - the detail is amazing.

This is my second run of this mosaic. In 2021, I tried a version with the ASI1600MM and Baader SHO filters, but the halos from the bright stars had me looking for alternatives. This year I acquired Astrodon Gen 2 LRGB filters, and 5nm SHO filters and the halos are gone! Also software has improved, and so have my skills.

About 77.5 hours of integration across all 6 frames and 6 filters in total, or 26.3, 20.6, and 29.6 hours for SHO respectively, and 12, 20 and 14 minutes for RGB.

Bortle 4 skies.

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.
