NGC 6946 - The Fireworks Galaxy

This is an interesting galaxy in a crowded star field. It is on the border between Cygnus and Cepheus, with about half of the galaxy in each constellation. It's name reflects the fact that there has been an unusually high number of super novae detected.

I'm rarely ever completely satisfied with one of my images, but this one comes close. The two issue remaining are some problems with blue registration in the corners. I should probably crop it a bit, but I haven't done so because I like the image with the full field, and the problem is not very obvious until you pixel peep it. The second issue is that the star field might benefit from a mild de-emphasis of the stars. I went back and forth over whether to do it or not, but decided not to at this point, because I really like the crowded star field for this object. It's unusual for a fairly large galaxy like this to have such a crowded foreground of stars.

The data for this image was captured at the Oregon Star Party between July 27 and 30, 2019. Acquisition details are as follows:

Telescope: Celestron EdgeHD 8" @ F/7

Camera: ASI1600MM-cool with Astrodon RGB filters

Mount: Astro-Physics AP1600GTO CP4 with Absolute Encoders

Sub exposures: 102x180 seconds red, 98x180 seconds green and 84x180 seconds blue.

Processing: PixInsight

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.
