The Ghost of Cassiopeia Emission/Reflection Nebula

We've been having a lot of cloud cover recently, so when I had two (very short) clear nights I jumped on capturing RGB to add to my existing Ha image. The RGB captures showed what I thought was very little signal, but when combined using Ha as luminance there was so much color I had to desaturate significantly to get the result here.

Drifting through deep space 600 light-years distant, the spectral image of a pale lavender ghost floating toward a bright blue star is another example of the endless variation of wonders the universe presents to us. The clouds of dust and gas are illuminated in relief by the star. Over an incalculable amount of time ultraviolet light pressure from the star has sculpted the clouds. The star is named Gamma Cassiopeia; it is the center star of the W-shaped constellation Cassiopeia.

IC59 and IC63 are a pair of emission and reflection nebulae that lie approximately 600 light-years away in the constellation Cassiopeia. IC69 (below and slightly left of center) is called the "Ghost of Cassiopeia." The very bright star, Gamma Cassiopeia, illuminates these great clouds of gas and dust.

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.
