Sombrero-Type Galaxies (Gary Imm)

Sombrero-Type Galaxies

I have always been fascinated by M104, nicknamed the Sombrero Galaxy. Some of my favorite features of this galaxy include:

•   Our near edge-on view, peaking at its disk so that the bright core is just above the centerline
•   The distinct thick textured outer rim of the galaxy
•   The glow of the core, encompassing almost the entire disk
•   The flocculent disk, with no distinct arms

It is both the galaxy and our apparent view perspective of it that makes it so special.

Although unique in its look, I have found that there are many objects which look similar to M104. I put this poster together of 25 galaxies which have a resemblance to M104. These objects make excellent imaging targets for longer focal length systems. But despite my extensive search, I could not find another "Sombrero-Type" galaxy which I liked as much as the prototype, M104.

Each of the object images on this poster has been posted to my Astrobin account. The links to each individual image are below in case you wanted to see more detail and a description of each object:

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.
