IC63

"the Ghost of Cassiopeia," officially known as IC 63, located 550 light-years away in the constellation Cassiopeia the Queen.

The nebula’s ethereal glow might remind people of apparitions in the dark. In reality, it's simply hydrogen that is being bombarded with ultraviolet radiation from the nearby, blue-giant star Gamma Cassiopeia, causing it to glow in red light.

The IC 63 nebula is not the only object under the influence of the blinding star, which unleashes as much energy as 34,000 suns. The Ghost Nebula is part of a much larger nebulous region surrounding Gamma Cassiopeia that measures approximately two degrees on the sky — roughly four times as wide as the full Moon.

When the Ha subs started coming in for this object the extent of the Ha was far more than just the main bright area of the nebula. This area is full of Ha it is just very faint compared to the main emission area. I processed this image to show some of the very faint background Ha as well.

It is a little different from most versions of this object, but I like the deep extent of the Ha gas I was able to bring out.

Hope all are well!

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.
