SH2-171 SHO

This is the first SHO image I’ve processed in a while as I’ve been busy, but also had PPS, (processing paralysis syndrome 🤪).  This is just what I needed to snap me out of that as what fun to process.  So many choices to make.  The tools are getting better, but that doesn’t seem to speed things up 😂.

Data acquired from my B7 backyard.  Like I mentioned, I’ve been busy lately, so I just keep imaging the same target night after night piling up the data…which from B7 is a good idea as got to be patient from light polluted skies. I find this large emission nebula compelling for many reasons, especially the pillars and the foreground dark dust clouds shaped by stellar winds, and of course the colorful gases.  This area kind of reminds me of the elephant trunk nebula (which I have data still to process due to PPS 😵‍💫).

Interesting from Wikipedia:  NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 3k light years away, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations

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.
