The Cygnus Loop with the Eastern Veil on the left, Pickerings Triangle (discovered in 1904 by Williamina Fleming and then duly named after her boss) and the Witches Broom to the right, is a favourite target in the northern summer sky. My first image with the Optolong L-Enhance filter, I have tried to keep as close to the natural colors as I could, while still boosting the Hα signal as well as the OIII. Stars edited separately.

I made the most of my 2 1/2 hour short summer nights and crammed a bit over four hours of exposure in during two nights.

Stacking and subsequent editing in Affinity Photo. Star separation in Starnet++.

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.
