The Sombrero galaxy is a very small world, 30% the size of our Milky Way. It lies about 30 million light years away from our home, which is actually not that far. The Sombrero holds the biggest supermassive black hole every recorded in any nearby galaxy. This also impacts its brightness, as it is the brightest galaxy in a 10 megaparsec radius of the Milky Way!
We spent a little more than 3 hours on it. We did 3 minute exposures instead of our usual 6, because of how small and bright it is.
You can see how we captured this target in Episode 6 of Galactic Hunter!
Camera: Canon 7D Mk II
Telescope: Orion 8" Astrograph f/3.9
Mount: Atlas EQ-G motorized Mount
Total Exposure Time: 3 hours and 9 minutes
Exposure Time per frame: 3 minutes
63 lights - 15 Darks - 15 Bias
LOCATING THE SOMBRERO GALAXY
The Sombrero galaxy can be seen from extremely dark sites with binoculars or telescopes, but is not an impressive target to look at. With a telescope of 10 inches or more, you may be able to distinguish the dark dust lane in front of the galaxy’s bright bulge.
To locate it, look for the constellation of Virgo and find its brightest star, Spica. M104 can be spotted just 11.5 degrees west of the bright star.
Getting farther from us at 1,000 km/s
Has a supermassive black hole with a mass of more than 1 billion suns
Brightest galaxy in a 10 megaparsec radius
SINGLE SHOT & PROCESSING OF M104
Below you can see one of our single shots of M104, which was stacked with its 61 other buddies to make our main image above! Notice how boring the 3 bright stars on the right look... Read more about them below.
The real challenge lies in the photo processing, as you must be sure to not make the core of the galaxy too bright otherwise you will end up with an image that looks overexposed.
Be sure to not only focus on the galaxy, but on those beautiful colorful stars on the right. This colorful asterism is called "The Jaws".
Galactic Hunter Episode #6 - The Sombrero Galaxy
The Sombrero Galaxy was the focus of the 6th episode of Galactic Hunter!
Discover how we captured this bright target below.
The Sombrero Galaxy is a tiny target that may seem difficult to capture for beginners, but its brightness and rather easy processing makes it really great for any amateur astrophotographer!
