Autumn Sojourn

At this time of year, the nights are long where I live, just north of the 43rd parallel. As winter approaches, these long nights provide me with the opportunity to image more than one object between dusk and dawn. I prefer to image when my subject is high in the sky, preferably over 60 degrees above the horizon. Several weeks ago, I had selected a target, but it didn't rise high enough until several hours after darkness had set in. Not wanting to waste valuable imaging time while waiting, I turned my attention to a young, energetic star forming region within the constellation of Cepheus, known as NGC 7822. Not knowing what to expect, I began capturing 12 minute subexposures. After several nights, I became more and more intrigued with the results I had been gathering. Later, I hand picked the best 36 hours of data to create this narrowband image in the SHO Hubble palette.

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.
