The Ghost of Cassiopeia IC 63

Steve and I are still in the early stages of understanding our new QHY268 camera and how best to optimise its performance and pointing it at a bright star for 600s Ha resulted in some halos within the master stacked Ha sub

. It's possible the FlipFlat also influenced the end result with incident light reflecting into the objective lens. The other channels with 300s exposures did not have any noticeable reflection patterns . . . phew. So I had to resort to some thuggery to blend the Ha and I am pleased with my result given the reflection pattern.

I am working through my data backlog (lots of family distractions at the moment) and have further data from the new QHY to process, as well as some older data from the previous QSI683 and even data from the FSQ106/QSI683. I hope to grab time over Christmas

.

I have endeavoured to keep an ethereal quality about the image and resisted pushing the Ha and Lum data too far in stretches or extreme local contrast enhancements.

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.
