This image was taken over two weeks in December 2023 with an ZWO ASI2600mm Pro through a Williams Optics Redcat 51 on an EQ6-R Pro mount.

The image comprises:

Ha: 220 x 300s
OIII: 221 x 180s
R: 20 x 180s
G: 20 x 180s
B: 20 x 180s

Total integration time was 30 hours and 20 minutes. The image was processed in Pixinsight and tweaked in Photoshop.

These are very, very faint objects. Even under Bortle 4 skies, I struggled to capture enough exposure time to bring out the details. I had previously imaged Sh2-224 by itself, but knowing that there were several other objects nearby, decided to try and capture them all in one image. The Redcat 51's FOV is just large enough (when coupled with the ASI2600) to capture them.

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.
