SH2-112 Over August

I had lots of travel I had to do in August. Naturally things got clear when I was away and also a bright moon. This image is the results of many nights from July-31 through August 21 with remote acquisition to the little Nexdome in backyard. 59.8 hours total SHO all in 600 sec subs.

Processing workflow went like this in broad strokes:

Linear fit O3 & Ha to S2. Made SHO. Initial color correction by choosing bright core as white reference. Masked stretch to 0.2 after mild touch up with color mask tool in PI. Extracted L and with that as mask pushed up saturation slightly.

Made superluminace and combining the linear HSO frames using Ha as reference. Masked stretch to 0.2 and then made SHO_L from that.

Go to PSD and do further selective color adjustements.

Back to PI for final ACDNR and curve adjustments. Fun to process such deep data which is hard to come by from my bright location.

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.
