IC63 - The Ghost of Cassiopeia

Probably one of the hardest target I have captured and processed, mainly due to the brightness of Gamma Cassiopeiae. Ring patterns from micro-lensing of the star covered the entire image and I had to use photoshop to remove it. The brightness of the star also made diffraction pattern from the primary mirror clip very visible, which doesn't look really nice. In addition, more Ha data is probably needed to better show the darker structure of the nebula.

Description: I blended the L component of RGB image with Ha image to reduce the noise in the diffraction pattern around gamma cassiopeiae (which is only present in the Ha image). The gradient around the stars also looks better with the RGB blend.

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.
