The Ghost of Cassiopeia (IC63) in hybrid mono/RGB

H: 129x120s
RGB: 15x10s each

IC63 is the "Ghost" portion of the Gamma Cassiopeia Nebulae (which also comprises IC59, not depicted here). The top edges of Ghost's cape glow strongly, illuminated by radiation from the bright star Gamma Cassiopeiae (aka Navi) just above the field frame.

Initially, I planned to do a simple Ha-mono version of IC63. But I also captured some short RGB subs to give me the option of incorporating RGB stars. Ultimately, I opted to lead with a non-traditional interpretation: the Ghost figure in ghoulish grey, set amidst a backdrop of RGB stars.

[For comparison, I've also included a simple Ha-mono version, and a more traditional HaRGB version (with Ha mapped primarily to red).]

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.
