Total integration time = 5.6 hrs (excluding [OIII])

Gamm Cass, 550 ly from us, is an interesting star in its own right. It is blue white, not quite a giant being 19 times brighter than the sun, yet 65,000 times as bright according to the ESA. It also spins at a tremendous rate, although its spin rate is hard to pin down as the ESA quotes spin in miles/hr for some reason (should be in rotations/day, degrees/day or even better – radians/day).
The star is always bright, but is unpredictably variable. This is likely due to a molecular cloud that surrounds the star a variably blocks some of the light. Parts of the cloud form the nebula we know as the Ghost of Cassiopeia that is a composite of reflected starlight and emitted light from the cloud, energized by radiation from the star. The emissions from the star are eroding and pushing the cloud away, forming the ghostly patterns of unstable displacement.
A series of [OIII] frames were obtained, but not used in the creation of this image, as they contained no information that was not contained in the Blue and Green filter results.
Gamma Cass is not related to Momma Cass who was also a star known for her singing about stars - shining and fading.

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.
