NGC 7822 - 2019

This object is a large emission nebula located 3000 light years away in the constellation of Cepheus at a declination of +67 degrees. The nebula spans 75 arc-minutes in our apparent view, which corresponds to a true span of 65 light years. The complex is sometimes referred to as Sh2-171 and Cederblad 214, although the true boundaries of these objects are slightly different.

The image incorporates data from narrowband filters, mapping emission from oxygen, hydrogen, and sulfur into blue, green, and red hues. Many "elephant trunks" - cosmic pillars of cold gas and dark dust – lie within this nebula. Notice that these trunks are all pointing towards the Berkeley 59 star cluster towards the center of the image. The powerful winds and radiation of this star cluster sculpt and erode the dense pillar shapes.

The brightest stars in the image are in the foreground and do not lie within NGC 7822. Also in the foreground is one of my favorite parts of the image, the dark dust clouds which seem to float by, obscuring but not completely blocking the beautiful bright emission background.

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.
