NGC 2359, Thor's Helmet collaboration

Awhile back, Kevin Wagner from the Unistellar USA group over on Facebook suggested that he and I combine all of our images of NGC2359, the Thor's Helmet / Duck / Baby Yoda Nebula. Kevin had 5 PNG images for a total exposure time of around 5 hours. I had around 280 minutes (4260 x 3.97-second subs) of raw FITS data. In addition, I threw in eleven 20-minute PNG's for another 220 minutes, though these PNG's were duplicates of some of the raw data. All told, between 10 and 13 hours of effective exposure time, depending on how you calculate it. I processed this in Pixinsight as a mosaic, cropped, noise reduction (NoiseXTerminator), photometric color calibration, deconvolution (sharpening), slightly tightened the stars and some final touch-ups to the color. Filters: L-eNhance and L-eXtreme. Unistellar eV-1. The mosaic was assembled in May of 2022.

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.
