IC63 - Gamma Cassiopeiae

So I got back from a 2 week cruise and while the cruise was fine, I managed to catch Influenza B. No fun. I noticed when I returned that I have 5 clear nights in a row and while those were over a full moon, I thought I might be able to find a target or two that would be far enough away from the moon so I could get some pictures. After a little searching I found two that looked like they might fit the bill. IC63 here and NGC2403 a galaxy just on the edge of being large enough for my Vixen ED103S to capture. I set up a sequence in NINA to shoot IC63 from about 7:30pm to midnight and then NGC2403 from midnight to about 5am. The fall skies are now dark enough, long enough to allow me to shoot that long.

This project allowed me to get just over 20 hours of imaging on both objects. My NYX-101 mount performed adequate all be it guiding under the full moon proved to be a challenge. The first night the moon was up fairly early. I wasn't sure I would get anything. Phd2 said it lost stars throughout the entire evening and total error guiding was just over 1'. All of that being said I managed even on that night to get about 50x300" images of each object that was useable.

IC63 proved to be just a bit of a challenge for post processing. Gamma Cassiopeiae is so bright (mag 2.1) that it really blooms about 30% of the image. Judicious use of masks and levels allowed me to assemble a reasonable image. With the 255 subs on this object the details in the "Ghost" came out quite nice.

Enjoy!

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.
