The Ghost of Gamma Cassiopeia

First image from the new back garden

We have thankfully had reasonable weather in the UK recently, with some good new moon imaging time. Light pollution is slightly worse than from my previous location, but the ease of setup hugely outweighs the negatives.

Navi was a tough one to control in this image, and I'm not entirely happy with the final process, but after four full re-works from scratch I have called it a day.

This is a HaLRGB image, processed using the emissionless technique to accentuate the background dust, with Ha re-added afterwards. There is an awful lot going on in the background in this region, with a nice SNR in the bottom-left corner showing in the Ha master, which looks like a mini-veil nebula. I have searched the SIMBAD database for this in Aladin but can't find anything; if anyone knows the designation of this, please let me know!

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.
