Ghost of Cassiopeia: dealing with unwanted reflections (Michele Vonci)

Ghost of Cassiopeia: dealing with unwanted reflections

I had these couple of hours of H-a narrowband data of the Ghost of Cassiopeia from last November which I never got to process...the three, possibly four internal reflections (see revision) from the star Gamma-Cassiopeiae always seemed an insurmountable obstacle. I don't know if this is always the case with this target or it's just my setup that creates these particular reflections - maybe an H-a filter with a narrower passband might help. Since I put a considerable effort into acquiring my data I never like throwing it away but I really didn't know what to do with it. Today I started to play with Photoshop using all the fancy patching and defect-removing tools and I managed to get something close to an acceptable picture, so quite happy after all!

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.
