The Sombrero Galaxy - M104

For the last few years, I have been collecting data but not actually processing and publishing. Some of the data that I collected has contributed to collaborations with my son, Josh Smith (on Astrobin), but the other data I collected has just been sitting.

Finally, I am starting to process some of this data. This first image was actually captured last season at three different locations.

I was really interested in capturing the "glow" of the Sombrero, but still preserving the details of the dust lanes and the oblique peek at the spiral structure. This image is an upsampled crop from a larger field of view. Imaging scale was approximately 1 arc-sec/pixel.

Eventually, I may upload some of my previously processed photos, but for now, I will probably just post the ones that are currently being processed.

I am not sure if there is a way to link to the images where I participated in a collaboration with Josh, but if I can do that, I will.

Thanks for looking! Comments and questions are welcome.

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.
