This is part of the Cygnus Loop, a supernova remnant of a star that exploded 10 to 20 thousand years ago. This object is at the western edge of the Cygnus Loop, and is a cloud of heated and ionized gas. The image is a composite of subframes taken through Hydrogen (Ha) (maybe?explanation below) and Oxygen (OIII) filters and then combined with Ha mapped to Red, and Oxygen mapped to Green and Blue, i.e. HOO. The subframes were collected in July 2023. I replaced the Narrowband stars with RBG stars, which were shot and processed separately.

My Mom asked if I could image this after she saw a picture of it in a magazine. I'm not sure if what I've done here compares to that, but I'm pretty happy with it. I am if the Ha was actually shot through an SII filter since I discovered that at some point I reversed them. Rather than research this further, I plan to return to the Cygnus Loop at some point in the future, and will do some captures and comparisons, possibly reshooting this object, or getting the appropriate data and re-processing. In the meantime 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.
