The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is cataloged as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.

Cigar Galaxy (M82), Bode's Galaxy (M81)

Bode's galaxy (M81) is a large bright spiral galaxy located approximately 11.8 million light-years from Earth in the constellation of Ursa Major. The Cigar Galaxy (M82) can be found right next to M81 and resembles a cigar of sorts. This pair of galaxies look amazing next to each other, and the differences between them is striking. NGC3077 completes this trio of galaxies, but is more of a faint blob compared to its neighbors. I took these over a 3 week period in by backyard in Cathedral City California.

Equipment used:
Celestron Nexstar 6se
6.3 focal reducer
AVX Mount
Canon 450d 600s iso800
Orion skyglow filter

Cigar Galaxy M82

Here are the 2 images stitched together, creating a wider field of view. I also was able to add some H-Alpha data to M81 which gives it a bit more color

This next image was taken with a Orion ST80 which has awider field of view and shows all 3 galaxies

Sharpest ever view of the Andromeda Galaxy

I ran across this image the other day, captured with the NASA/ESA Hubble Space Telescope. This is simply the most beautiful picture of the Andromeda Galaxy, or any Galaxy for that matter, that I have ever seen. The full size original is a whopping 4.3 GB, but is completely worth every bit of bandwidth. This image shows over 100 million stars and thousands of star clusters, and I just can't stop looking at it! #Mindblown

You can download various sizes from the Spacetelescope.org website
