Fireworks Galaxy - NGC 6946 (OSC HaRGB)

NGC 6946, also known as the Fireworks galaxy, is located in the constellation Cepheus approximately 25 million light years away. It is a face-on intermediate spiral galaxy with a small bright center. The Fireworks Galaxy is so-named because supernova are known to be a frequent occurrence there.

This unguided image was captured, in a Queen Creek (Arizona) Bortle 7 backyard, using a Celestron EdgeHD 11" telescope with a 0.7x focal reducer. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MC Pro using a Astodon OSC UV-IR Cut and IDAS NBZ filters. The image is comprised of 100, 120 second exposure length frames. It was captured over 3 nights (5-24-2022 to 5-29-2022). The images were stacked/processed in Pixinsight and fine-tuning done in Photoshop.

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.
