Description

The Sombrero Galaxy is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs from the Milky Way galaxy. 
It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.  Size: 9' × 4' Distance: 29.35 million light years
Magnitude: 8.0 Stars: 100 billion.

One more rare night with very good seeing and unusually, no risk of rain,  so I left the rig running on M104 until 5am which makes a huge difference to how much colour I could wring out of it.

The new Pixinsight Weighted Batch Process does not like less than 15 subs per channel to provide Drizzled data so after saving the selection to a CSV file in Subframe Selector,  I cheat and while the rejections are being whisked away, I pick the best subs for each channel and clone them the required number of time to get drizzle to work happily (Yes cheating!). The process is part of an Excel spreadsheet I wrote with a lot of VBA code to manage Pixinsight and that cheat is now built in and takes no time at all after the rejects are dealt with. Working with Drizzled output has some major advantages in processing.

Astro Imaging in the 21st Century

Of course simply getting a lot more quality data would be the way to go but the realities of the current climate, and blazing Star Link satellites, can get in the way.
It was not that long ago 2-3 good nights a week were normal but now its more like 3 good nights a month if your lucky. Dang! I picked the wrong century to get pot committed on Astro Imaging.
But if I rented time on a rig on a mountain in Chile where would be the fun in that?
