Ghosts in Cassiopeia (IC59/63)

IC 63, also known as "The Ghost of Cassiopeia", is an area of Hydrogen clouds and dust located 550 light-years away in the direction of the constellation Cassiopeia. The material in this region is incessantly bombarded by ultraviolet radiation from the nearby variable star Navi (Gamma Cassiopeiae, top left of my image), which is only 3 light-years from the nebula and is slowly eating away at the ghostly cloud of dust and gas. This blue-white giant star is the central star of the "W" asterism formed by the constellation Cassiopeia.
At the bottom left of my image you can see IC 59, another region of gas also excited by the same star.

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.
