M104 (Sombrero Galaxy)

I have been working on this image for a while, started on April 30th using my SW 190mm Mak/Newt. But as I mentioned earlier it is out of commission so I switched to my ES 127mm triplet. I was having either some tilt or collimation issues with my 190 and my stars looks awful. So I just took a few images a couple of nights ago with my refractor to get some nicer stars. I used StarX Terminator to get a starless image taken with my 190mm and then added that as a layer to my 127mm image. This is a tough target to process to get detail and not blow out the core, which is a very notable part of this image. If you zoom in, you can see some spiraling between the outer edge and the core, so I was happy with that.

M104 is around 29 million light year away and is estimated to be 130,000 light years in diameter. In the 1990s a research group indicated that M104 has a supermassive black hole 1 billion times the mass of our Sun.

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.
