One Night with NGC7822

This is NGC7822 in Cepheus.

We had a break in the weather for one night, so I figured that I would give this object a try. I captured this with my wide field setup, a Stellarvue 80mm triplet with a reducer/flattener at F/4.8. The camera is an ASI2600MC Pro with an Optolong L-eXtreme filter. The mount is an Astro-Physics AP1600 with Absolute Encoders. Processing was done in PixInsight.

Conditions were windy (about 20mph) with a milky grey sky from a nearly full moon. There are 192 x 3 minute exposures, unguided. There was a severe east-west gradient in the green and blue channels from the nearly full moon. The nebulosity was virtually invisible in the raw, undebayered data from the camera and only came out in processing.

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.
