NGC 6946 Fireworks Galaxy HaLRGB

I was excited to give the Firworks Galaxy a full go with the ASI 1600 MM for RGB. I had planned to wait for a new moon for the luminance data, but the current wild fire haze has made transparency too poor to capture. On a whim, desided to add 2.5 hrs of RGB data from my ASi 294 MC with 5 min subs in gray scale for the lumiance. Not a perfect idea, but I am pleased with the results. The Hydrogen alpha data on the other hand was some of the best I have completed thus far. More worked to add to this project, but I am excited about it so far.

The fireworks galaxy is a spiral galaxy that has had 9 supernovas observed in the last 100 years. It's located approximately 10 million light years away, but isolated from other galaxies from our local group. The galaxy itself measures 40,000 light years across.

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.
