M16 - The Eagle Nebula
I took this image of the Eagle Nebula several nights ago. I am afraid I have not been very active as far as imaging goes... other tasks have taken priority. This was a quickie, done with 6 ten minute images shot with my big 9" telescope at F6.3. I used my trusty old Canon 300D DSLR set at ISO 800.

M82 - The Exploding Galaxy?
This is a pretty commonly imaged galaxy. It is also somewhat of a mystery. Nobody quite knows exactly what is happening with this galaxy. It emits massive amounts of radiation and energy, and for many years Astronomers thought it was "exploding" through some largely unknown process. Now that we can see it better with more advanced telescopes and imaging systems, the mystery only deepens. Visibly, it appears to be a very distorted spiral, seen edge-wise, but the center is almost obscured by vast clouds of Hydrogen gas that appear to be streaming out of it. On closer inspection (like, with the Hubble), it becomes debatable whether these clouds are in fact coming from the galaxy, and are simply situated in between us and M82. The fact remains that this galaxy is highly distorted by it's larger neighbor, Messier 81, and whatever is taking place is more than likely because of this distortion.
This galaxy has another close cousin, NGC 1275, which appears to be doing almost the very same thing, but is located in another region of the sky - however, it has no larger neighbor to distort it.

Eight 11 minute sub-exposures.

Bode's Galaxy - Messier 81
This large galaxy is located in the northern sky, in the constellation of Ursa Major. It is quite bright, and can be seen with the naked eye on a dark night. It is the major member of a large group of smaller galaxies all orbiting each-other. This is about 1 1/2 hours worth of images shot with the big 9 1/4" scope and my DSLR.

M101 - Distorted Spiral in Ursa Major
I shot this photo of Messier 101 last night using the big 9.25" scope. M101 is a large spiral, with a distorted arm. To the upper left, out of the frame, is a smaller galaxy that is more than likely the cause of this distortion. M101 can be seen with the naked eye on a good dark night. The photo came out pretty good even though a stiff breeze was blowing and bumping the camera all around. It was shot using my Canon 300D and a .63 focal reducer. 13 images of 8 minute duration median stacked.

M51 Whirlpool Galaxy with the Big Scope
M51 is a nearby galaxy undergoing a close pass with a smaller neighbor. The smaller galaxy is being ripped apart by the tidal forces generated by the encounter.
I took this photo of Messier 51, the Whirlpool Galaxy using my biggest telescope, the Celestron 9.25" inch Schmidt-Cassegrain and my Canon 300D DSLR. It is a median stacked composite of five 10 minute images. It is a little grainy, and the stars are a bit wonky because the wind was blowing. Overall I am pleased with the color it captured. I had planned to capture more than just five images, to reduce the graininess, but a windstorm kicked up and thwarted my plans.

M100 - Two Armed Spiral in Coma Cluster.
M100 is a spiral galaxy near Coma Berenices. It sits amongst a vast cloud of nearby galaxies, in a very rich section of the sky. It is considered a classic spiral, and has a very bright core. In a telescope, it almost looks like a star with a hazy patch around it. It known for producing at least two well known Supernovae over the last decade or so.
I took this with my Canon 300D DSLR using my big C9 and a .63 reducer. It is 7 eight minute images, more or less. The wind was giving me problems, so the stars are not perfect. I eventually gave up and went inside. Wind is awful to fight against - you can't win.

M94 - The Eye in the Sky
I shot this picture of Messier 94 with my Canon DSLR and my big 9 inch Schmidt-Cassegrain scope. This galaxy is considered an active galaxy, and has a very violent nucleus. It is theorized to hold a super-massive black hole. It is very dusty, and the collapse of the dust into the nucleus is thought to be producing an outburst of star formation, called a "Starburst". The faint glowing cloud surrounding it is a very dim halo of stars, offset from the central arms and "starburst" ring. The whole effect makes it appear similar to an "eye" floating in space.
This image is a compilation of nearly 2 hours worth of images.
