Messier 104, the Sombrero Galaxy, is one of the more distinctive galaxies in the night sky. That large central bulge, the prominent dust lane that surrounds it and it's nearly edge on orientation to us give it a very dramatic appearance.

I wasn't expecting too much from this image -- that large central bulge seemed very much like an elliptical galaxy's featureless blobiness even though M104 is a spiral galaxy. However when I saw the data come in I was very pleasantly surprised. There is detail in the dust lane and hints of structure in what little we can see of the disk. It's all on the more subtle side but worth spending time examining!

Here's how I processed it:

RGB combination
dynamic crop
DBE
SPCC
blurxterminator
starxterminator (extracting unscreened stars)
noisexterminator
GHS
LHE (strong mask)
MLT (very mild sharpening through strong mask)
pixel math in stars

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.
