NGC6946 - The Firecracker Galaxy

Doing some research on improving my imaging and more specifically, data collection. One item I kept coming across was using longer subframe times that I was using with my CCD. In the past the typical LRGB subs were: 300:240:240:240. My Lum would not be too bad for processing, but the RGB were very noisy and tough to deal with. Even when moving from a bortel 6 to 4 location. So with this project I went to 600s for all subs. Also I switched from doing the RGB at 2x2 binning to 1x1. I am really pleased with the results!

NGC6946 or Caldwell 12 is a classic face-on spiral galaxy. It gets its nickname of the Firework Galaxy because of 10 known supernova discovered in it in the last 100yrs.

I managed to also get a handful of background galaxies in this image, the two most prominent are in the top left. So far I have not had much luck finding any information or even catalog names for them. Guess I need to improve that area of my imaging also.

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.
