Ghost of Cassiopeia SH2-185 IC59 and IC63

This is one of a series of three "Halloween" themed nebulas that I have been working on for the last couple of months (Ghost of Cassiopeia, Wizard Nebula and Witch's Broom). Time to share now that we are getting nearer to the holiday. The three are all processed using a modified SHO palette.

550 light years away, this is a somewhat eerie nebula along with the Gamma Cassiopeia blue-white subgiant variable star, 19 times more massive than our sun. Illumination from the star gives the nebula an eerie glow (this may be a combination of both direct Ha emission and reflection/light scattering).

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.
