M95 barred spiral galaxy in Leo

Revision title: Cropped image

This crazy wet Arizona winter and an even crazier daytime schedule has reduced my processing time...but I finally finished an image. Three more are waiting in the wings but who knows when I'll get to them. At least the observatory is collecting data on the few clear nights we are getting here.

This image was a particular challenge to get color balance acceptable (at least to my eye). Using Specrtrophotometric Color Calibration, the final image was just too green and dingy for my taste. When fitting the color calibrated stars, there were very few in the field of view and I suspect the color fit statistics were just not good enough to get an accurate color starting point. I went back and used a standard Color Calibration on the galaxy and got a more pleasing result with yellows in the barred spiral region and some blue hues in the spiral arms. Producing "standard" color, image to image, for these galaxies is my next processing challenge to find a way to develop some skill in getting reproducible colors.

The other oddity I observed in my stacked color images was some resolution of "knots" in the galaxy core. These were not present in the brighter Lum master stacks, but were present in the R,G,B masters. Real or some odd mathematical phenomenon...I don't know. You can see it for yourself if you look close at the core.

Enjoy and clear skies everyone!

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.
