M 104, The Sombrero Galaxy - Lemonade out of Lemons

This is an attempt to salvage an imaging session gone bad. Our trusty astro group headed out to Picket Post Trailhead last night to take advantage of the good weather forecast and Bortle 4 skies. Someone made the comment about this being the best imaging conditions in months to which we all agreed. Well, everyone but the weather gods.

About 3 hours into the session, winds came out of nowhere and sub arc second guiding suddenly spiked to 4+ seconds. I think we must have experienced the edge of a high pressure system moving in as the ambient temperature spiked up with the wind and we all saw our camera coolers jump from 30% to over 50% load. While interesting to witness the weather phenomena, our imaging session was cut short.

I decided to image M 104 since I don't have a good view of it from my backyard. My total acquisition time was far short of what was needed but I decided to forge ahead and see if I could make some lemonade out of the lemon session. I was not able to finish my blue run and didn't capture any luminance. As a result, I used the limited RGB data to create a synthetic luminance channel. Hopefully I can add more data to what was captured last night so that I can try and resolve more detail.

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.
