IC 63 - Gamma Cas Nebula

IC 63 is a reflection nebula illuminated by the nearby bright star Gamma Cassiopeiae. The designation "IC" stands for Index Catalog, and IC 63 is the 63rd object in the Index Catalog of Nebulae and Clusters of Stars. The object is often referred to as the "Ghost of Cassiopeia" due to its ethereal appearance. Gamma Cassiopeiae is a variable star that exhibits irregular changes in brightness, and its intense radiation causes the surrounding dust to glow faintly, revealing the intricate patterns of the nebula.

This bright target is a fairly easy target for newbies or for those who want to accomplish a full integration in one evening. Beside the reflections in RGB channels, this target emits strongly in the Ha frequency which can be used to bring forth more intensity in the reddish regions. It is easily captured even in heavily light polluted skies.

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.
