The Ghost of Cassiopeia - a HaRGB image

Revision title: The Ghost of Cassiopeia HaRGB rev2.0

The Ghost (IC 63 & IC 59) is an extremely faint emission and reflection nebula in the Northern constellation of Cassiopeia at a distance of 550 light years from Earth. The nebula is crafted by the intense stellar winds of the central blue supergiant star γ Cas. This star is 19 times more massive and 65.000 times brighter than our Sun. The hydrogen within IC 63 is being bombarded with ultraviolet radiation from Gamma Cassiopeiae, causing its electrons to gain energy which they later release as hydrogen-alpha radiation — visible in red in this image. IC 59 exhibits a blueish color due to the fact that it reflects starlight from the massive star.
Both nebulae are being eroded by the intense winds of Gamma Cas and in time, will probably disappear.

Image details: The image represents a total integration of 20 hours - a HaRGB combination

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.
