Lower's Nebula (Sh2-261)

Lower's Nebula (Sh2-261). I had three consecutive nights of clear skies this past weekend, and I spent them on Lower's Nebula, a humble emission nebula in Orion that is frequently overlooked in favor of its more famous and spectacular celestial siblings.

This image stacks 226 x 120s subs across the three nights, for 7.5 hours of integration. It took all three nights to draw out its full character and charm--not to mention Astro Pixel Processor, which I recently adopted, and which delivered a high-quality image to work with in Photoshop (Revision A) and eventually PixInsight (Revision C).

(Captured by MRE: C6, AVX, Hyperstar, ASI183MC Pro, Optolong L-Enhance filter. Processed by MRE: Astro Pixel Processor, Photoshop, Star Xterminator, Gradient Xterminator, and Topaz DeNoise AI. Reprocessed with PixInsight, StarXterminator, and NoiseXterminator.)

Description: This was the first project I completed using an EQ mount, and it's satisfying to see that I can still revisit the data and bring something new to it. This is a spur of the moment reprocess, taking advantage of a couple more tools. This time I've added BurXterminator and Bill Blanshan's and Mike Cranfield's Star Reduction script to the arsenal. I think they make a great deal of difference here, giving the nebula a greater chance to shine.

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.
