LDN1657 Dark Nebula

Taken from my Bortle 7 skies in my backyard using the Optolong L-Pro filter. To minimize star saturation, I used short exposures that just swamped the read noise of my camera. I'm liking the results that I'm getting using this approach, however it does increase the acquisition and processing time due to dithering and the number of images required to accumulate enough data for processing. Guess, I need to work at shorting the recovery time of my dithers.

Description: Finish reprocessing my LDN1657, I had to crop it a little more because I had a lot more low signal around the edges that I didn't account for in the original version. I'm pleased with results of the reprocessing. In my opinion this version has a better background and stars. The original may have been over-processed a bit, so I toned it down a little with this version.

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.
