SH2-261 Lower's Nebula

Lower's nebula is named for Harold and Charles Lower, the pair who discovered the nebula in 1939. In terms of apparent size it's roughly 2x as large as the full moon, and is located in Orion's club/sword.

Southern sky is not great from my backyard, so I had to chip away at this a few hours at a time. Fortunately it is very high in the southern sky, so cleared my roof and my one problematic pine tree in the southeast. Nice, strong signal from Ha and Sii. But, as is often the case, Oiii was very weak and required much more than the others. C&C always welcome. There is an interesting Oiii bubble/shell around the central star that I tried to bring out.

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.
