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.

Here are the planets Venus and Uranus in the dawn sky this morning (May 13th), At the time they were separated by about 3.5 degrees, but the gap will reduce to about 1.3 degrees on the 16th May.
With apparent magnitudes of -3.94 and 5.92, respectively, Venus appears 8800 times brighter than Uranus!
Notice the blue/green colour of Uranus.

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.

Took my new Sony A7CII out to my favorite dark sky location to see how it handles the night sky. It did wonderfully! No more star eater bug, Sony finally fixed it!

On this night I captured Comet Hartley with my camera piggy-back on my telescope, through a zoom lens (Canon T1i, 300mm, F5.6, ISO3200). It's a wide view, 4 full moons could span the height of this image.
40x 30 second exposures were shot between 11:17pm and 11:50pm PST, 20 minutes total exposure time over 33 minutes.
Stacked to hold the comet still with Deep Sky Stacker 3.3.3 b25, 'Kappa-Sigma' formula which in this case represses the star trails. This version brings out more of the glow of the comet, and a hint of a tail going off to the top right.
On this night, Comet Hartley was in the constellation Perseus, shining at about magnitude 5.7. It has a distinct green glow but no distinct tail.
Canon 5D3 with Celestron CGEM 1100HD and 0.7x focal length reducer. Manually guided using Celestron's off-axis guider and Orion's 12.5mm illuminated reticle eyepiece.
Stacking (using Deepskystacker) of 11 shots taken at ISO 800 with 10 minute exposure (plus dark frame for each). I took 16 shots of the sky in the morning for the flats to correct background brightness variations.
Seeing was very good for Wisconsin, lots of detail in this one.
- www.kevin-palmer.com - I decided to go back and re-process this image from the middle of summer. This part of the sky is just filled with interesting objects to observe. On the bottom is the large "Lagoon Nebula". The multi-colored "Trifid nebula" is above that, with the star cluster M21 above the trifid. The large star cluster at the top right is M23. This is a stack of about 65 pictures taken with a Takumar 135mm f2.5 lens. All shot at 4 seconds, f2.5, iso 8000.
First picture from my new photographic challenge.

Stack of 51 images (lights) 30s exposure ISO1600 and 24 darks. Stacked in DeepSkyStacker, developed in StarTools demo. Some horisontal "tracks" in the image, not sure what have caused it. I was "plagued" with Aurora this evening, so maybe the tracks are remains of that. I am very sure the colors are very much of.
Pretty happy with my first attempt, LOADS of things to learn, not least in the fine art of post processing.
This is a 6-minute stacked image from three 2-minute exposures. I'm looking forward to my next dark sky outing. Hopefully Monday will be clear for the peak of the Perseid meteor shower. The AstroTrac is too cool. :)
Oh, and the processing is quick-and-dirty. I should really have spent a bit more time getting the colour tweaked accurately.
The Rosette nebula imaged at our local Stargazing Live event in Ipswich on the evening of monday Jan 16th.
Whilst the 300 (yes, 300!) people were all queing up to look through some of the scopes set up I was showing them images taken on my modest imaging rig via my laptop. In the mean time the rig was snapping away at the Rosette nebula.
This is a total of 23 X 6 minute exposures with matching darks and flats applied. The full details are as follows:
