Sh2 265 HA RGB

From Galxymap:

This diffuse HII region is part of the Barnard 223 dark cloud in the southern part of the Lambda Orionis ring (most of which forms the huge Sh 2-264 HII region).

Avedisova places it in star formation region SFR 195.06-11.99 as part of the Lambda Orionis ring complex along with Sh 2-263, Sh 2-264 and the dark nebula LDN 1582 (Barnard 32).

The position of this nebula in the BFS Vizier catalog is currently incorrect.

This diffuse HII region is part of the B223 section in the southern part of the Lambda Orionis ring. However, this region is not ionised by Lambda Orionis itself. Instead it is probably ionised by stars in the Ori OB1b association. [1]

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.
