M51 - The Whirlpool Galaxy

M51 taken with my new ASI294MC-Pro camera. Since I do not get a lot of imaging time, traditional LRGB with a mono is tough to do. I figured a cooled OCS would increase my productivity so I purchased this camera based off a couple reviews and images I had seen.

I am struggling with calibrating and processing with this camera. The background is "large scale blotchy" have doing a ton of reading and processing, I found not using flats really made a big enough difference that I could complete processing to a point of being happy and posting it.

So the PI workflow was pretty basic: Calibrate, debayer, register, intergrate, drizzle 2x, DBE, BN, CC, MSLT, HT, LHE and then off to PS for some levels and curves.

Still have a lot of work to do, but now I have something to go on. My flat setup is a DYI with a sketching LED panel deal I got off Amazon. So I need to revisit how I do flats. Processing around no flats was not that bad in PI with DBE, but a couple of dust donuts are in there. Actually one I worked on PS with the stamp tool also. Hope it is not too apparent!

Made a commitment this year to image more from dark skies and not my red zone backyard, so I decided Thursday at work to haul all my gear for a night of imaging since the forecast was looking good. Hardest part was having to work the next morning, so I was dragging at the office the next day! But going from a SQM 18.1 sky to 21.1 in roughly 50min is well worth it!

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.
