Lambda Orionis Ring (Sh2-264)

Sh2-264, aka The Angelfish Nebula, aka the Lambda Orionis Ring, is a molecular cloud and Ha region, which can be seen in the northern region of the Orion molecular cloud complex (OMCC). According to Wiki the OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. When posting the image I realized that there are surprisingly few images on Astrobin focusing on this big structure and including all of it. This is a three panel mosaic with a lot of overlap taken with my Samyang 135. To this I have added RASA data to the highlights of the nebula.

To the left of the main object, the planetary nebula WHDS 1 (aka WeDe 1) can be seen, while to the right the Strawberry Nebula (Sh2-263) is shining in red and blue.

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.
