M 63 Sunflower Galaxy LRGB , the "state galaxy" from rural Kansas Skies

I had a hard time deciding what object to capture next. I finally decided to take a crack at M 63, having live in the Sunflower State for most of my life. I found this target to be challenging and will need reworking. This was my first light use the Astronmik deep sky RGB filters in combination with a new Astronomik L2 filter for luminance. My flats failed for by RGB by causing too much correction and I am working on fixing this problem and plan to complete a completely new edit.

The Sunflower Galaxy, M63, is a large spiral galaxy that resembles a sunflower in its appearance with loose spiral pattern, flocked spiral arms, due likely less external gravitation forces that tight spiral arms like M51. M63 is also part of the M51 galaxy group. M63 appearance is similar to that of the more famous M33 with its flocked spiral pattern. The galaxy is an estimated 37 million light years away and 90,000 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.
