This image is sort of an experiment to see if some good Luminance data can improve some not so good RGB data.

I originally did this image back in January of 2019 using my 8" Newt and an ASI1600mm. I had little experience doing RGB work with a mono camera and I still did not even know how to properly focus my instrument. Amazing how such a seemingly simple thing can be so difficult for a beginning astrophotographer.

In any case, there have been several times when I have no opportunity to image anew, I went back and played with this image. The last time was about a month ago when we had all of the smoke in our skies from the California wildfires. While I was doing that re-process, I got the idea to re-image the luminance channel and see what comes of it and this is the result.

I added about 3 hours of straight luminance data acquired using a C9.25 with the HyperStar lens with an ASI183mm and a UV/IR cut filter. I am reasonably pleased with the outcome.

I hope you like this final effort with this data and thanks for obliging me, lol...

Any comments/criticism always welcome and Clear Skies!

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.
