M104 - The Sombrero Galaxy (Cropped Version)
So far, this is my Favorite object! I remember the first time I saw the image of this galaxy made by Hubble Space Telescope, I was simply speechless. Studying this galaxy more closely, I learned about incredible amount of globular clusters that surrounding it and it got me wondered, how many of them I would be able to catch. Also, I really wanted to see if there is something hiding under the large halo and if some finer details can be recovered. As you can see, the result is simply amazing.
This is also have been the most invested object. I have spent two months hunting down this galaxy, during which I've managed to image it for 4 days. The processing have been split in to two versions and each of them have been processed many times until I got it to my satisfaction. Annotation of Globular Clusters were very time consuming. I used Simbad and Ned databases to verify the globulars visible on my image and to my surprise, I've managed to mark 110 of them and dosens more on the Widefield image! I have never spent so much time on any other object. It's just amazing to see so many globular clusters swarming the galaxy. Trully incredible.
Unfortunately, after all of that time spent on imaging this object, only 16 frames, 4 hours of total exposure, were worth of stacking. I decided not to stuck with it and image it next month again, but to process what I have and move on to the next object. But the available data, were far from being bad. Of course, I wish I could have more hours to improve the SNR but what I had in my hands, let me process it to the images you see now.
Don't forget to check out the Annotated version to get the impression of the globulars swarm.
