Cygnus Loop

After completing my first two projects with the QHY600, I moved on to a second set of targets to work simultaneously. The first half of the night I'd image the Cygnus Loop and then switch over to NGC 7822 until astronomical dawn. Keeping the camera rotation at the same angle enabled me to use just one set of flats for both targets. I still hadn't fully resolved my backspacing, but at the time I was actively searching for a set of suitable spacers that would provide me future flexibility. Additionally, I was still unaware I had reflection issues. With persistent clear skies, I was in acquisition mode and hadn't taken the time to stack any subs to realize the issue. With a week plus of clear skies, I was able to knock out both targets and move on to the next set of targets.

I marked the HOO version of the Cygnus Loop as the final version since I much prefer the more vibrant reds and blues over the SHO version.

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.
