NGC 4312 LRGB

This is an experimental potshot at a relatively small galaxy for a 5" scope--NGC 4312 is a spiral galaxy typically framed with its optical neighbor M100. This is a crop from a larger FOV that includes M 100 as well as a bunch of other galaxies. Several tiny, distant galaxies can be seen near the left hand edge. Seeing was quite good for much of this shoot. If I had known this galaxy would be depicted with so much structure and color, I would have collected a lot more data. I know it's not the cleanest image--but its the best that could be produced with this data without turning it into a cartoon. I will work on reducing the stippled glow. I think I can do it with some judiciously crafted masks and some gentle curves adjustments. For now, just don't get too close to the screen. Its not bad if viewed from 3 feet or so. i suppose that is normal viewing, but I usually scrutinize up close (being nearsighted lends itself to this). I am looking forward to galaxy season next year, which I will partake in with the C11Edge.

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.
