Messier Object 42, The Orion Nebula
Anyone who has ever looked at the constellation Orion has seen these objects
There is more than just M42 in this shot.
Actually, it's widely believed that most of the nebulae in Orion are all part of the same cloud of gas and dust, so I guess it could be just one object...
Anyhow, the technical stuff:
2 minutes, 13 seconds at ISO 800
Canon EOS 30D
Prime Focus on a 10" (254mm) Newtonian Reflector
1016mm Focal Length (Which makes it F/4 for those of you keeping score)
This is actually a collection of these frames, stacked in DeepSkyStacker.
I used a 5 minute dark frame, which may have actually resulted in a slightly inaccurate final picture, since it's twice as long as the total light frame exposure.
I captured about 30 minutes worth of various exposures, playing with ISO and expsore settings.
Perhaps I'll get around to stacking those at some point.
Here is the exact same stacked result with some slightly different modifications in Photoshop.
It's late, but soon I'll post the original copy, before I messed with saturation. It barely has any hint of color, but shows a couple details better.
An untracked/unguided, wide-field view of the constellation Leo the Lion and the planet Mars. This photo also captured the small center cores of the galaxies M105, M96, M95, and NGC 3384 which are members of the galaxy group known as the Leo I Group (or simply the M96 Group). A 100% scale crop of the area in which the galaxies appear can be seen in my photo entitle "Mars and the M96 Group of Galaxies (5 Second, Untracked Exposure Stack)."
This image is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size). Within the light box you will also be able to see the central outline of the stick figure which represents the body and head of the lion.
Captured on December 7, 2011 between the hours of 4:20AM and 4:30AM PST from a significantly light-polluted, near-center-city location using a Nikon D5100 DSLR (ISO 4000, 5 seconds x 64 or just over five minutes total exposure integration time) and an AF Nikkor 35mm 1:2D lens set to aperture f/4. Image stack created with DeepSkyStacker (64 "light" frames and 32 "dark" frames) with final adjustments done in Photoshop CS3. Star diffraction spikes were enhanced in Photoshop CS3 using ProDigital Software's Astronomy Tools.

The Rosette Nebula is a large spherical H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.

The air temperature was measured by QCZ as varying from 105 F to 95 F during these images were being taken. I have never taken any long exposure images in such high temperatures. As a result, the original raw images look terrible, teemed with hot pixels, since my camera was uncooled. I could have used exposure time >10min but I was afraid that the hot pixels could not be removed properly in the calibration process.
Comet Lovejoy continues to show nicely in the hours before dawn, passing in front of the stars of the constellation Corona Borealis. It is currently around 4th magnitude which is bright enough to see with the naked eye in a dark sky. Unlike the photo from a couple of nights ago, this one is a stack of 15 exposures which reveals a bit more of the growing tail. Our good observing window will be closing over the next few days as the Arctic ridge weakens and cloud starts to roll in from the Pacific. Prince George, BC. Dec 06, 2013.

From the National Bridge website:
The beauty of the night sky, the lack of light pollution, and the National Park Service commitment to night skies as a natural resource, led the International Dark-Sky Association this spring to designate Natural Bridges National Monument as the world’s first International Dark Sky Park.
Natural Bridges is one of the darkest national parks in the country according to a comprehensive study of night sky quality conducted by the National Park Service.
Just how dark is it? “It’s the only Bortle class 2 sky they’ve documented,” said Chris Luginbuhl of the U.S. Naval Observatory in Flagstaff, Arizona., and a board member of the International Dark-Sky Association. “In plain English that means it’s the darkest or starriest sky they’ve seen while doing these reviews. The Bortle system is a 10-level scale with one and two being the darkest skies and 10 having the most light pollution.”

After a very successful imaging session last night, under the dark skies of Joshua Tree National Park, here's the first result. This shows the famous Flame Nebula (NGC 2024), which is below the really bright star Alnitak. And the even more famous Horsehead Nebula (Barnard 33) to the upper right of Alnitak, which resembles a horse's head. This one turned out better than I expected. Many more to come. :)

10 Things:
From a relatively dark site I managed to build this wonderful image of the Orion Nebula in the constellation of Orion.
A rough shot, trying out my telescope the night I got it back from repairs. The repaired telescope still has it's quirks, but is much improved.
The mount wasn't properly polar aligned, so the stars are trailed slightly in this stack of 26x 30 second exposures, shot at iso800 and 1600 on a Canon T1i at prime focus on a 10" Meade SN-10AT telescope with an Antares ALP light pollution filter. 13 Minutes total exposure time.
This was also my first night trying out the light pollution filter. I've realized that It's not actually the filter I intended on getting, it cuts out quite a wide band of the visible spectrum. Light pollution is cut out pretty well, giving a much darker background, but it made it hard to adjust the colours in this image.
The Double Cluster is a pair of young open star clusters about 100 light years apart from each other, 7600 light years from earth in the constellation of Perseus. They are just visible to the naked eye from dark skies. They span an apparent area on the sky similar in size to the full moon.

So this is the first astro photo I've taken where I can clearly see a galaxy. I think I can see Andromeda on the right hand side just above the sloping roof line of the house. Wish it was this clear at home!
Also in the shot: The Pleiades (M45), Cassiopeia and a bunch of others. The white glow at bottom centre is from Jupiter.
