Angelfish Nebula, SH2-264

The Angelfish Nebula, also known as Sharpless 264 and the Lambda Orionis Ring, is an HII region in the upper part (from Northern latitudes) of the Orion molecular cloud complex.

It was imaged over 6 nights as a 6 panel mosaic as the FoV with my Redcat was too small to capture the whole object. The processing was a challenge as there were varying amount of light pollution from moonlight including a full Moon over the acquisition period.

Each panel was RGB 30 x 60 secs each + 80 x 120 secs Ha , 5 hours plus for each of 6 panels totalling over 30 hours of integration, my longest project on a single target yet!

Captured over 6 sessions on 22, 24, 25, 26, 27 Feb, 19 Mar 2022 from my Bortle 5 back garden with Redcat 51 on an iOptron Skyguider Pro (not guided) with ASI 1600 MM Pro mono camera with R, G, B, Ha filters.

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.
