Lower's nebula in Orion

There are quite a few interesting HII regions at the border between Orion and Gemini; the Monkeyhead, The Jellyfish, this one, Lower's nebula etc. This little nebula was discovered in 1939 by father and son Lower, and thus the name. Distance from Earth is about 3000 ly.

My HHO image is based on about 6 hours of data from Earlier this year. Most images are from around March 18, 2022. The signal in Oxygen light is not very strong so it was a bit of a challenge. I probably pushed the processing a bit too much for the SNR that I got, but I like it anyway.

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.
