Photographed from Granger Lake, TX (Green Zone)
After years of dabbling with astrophotography (with little success), finally rigged up my old Meade 8" LX200 classic with an autoguider, did some serious homework, and came out with this image of the dumbbell nebula taken from my backyard in Austin, TX.
The autoguider (orion SSAG) made all the difference as I could get my exposure times way up w/o any tracking errors. It was awesome and tracked perfectly! I used the autoguider and phd running on my netbook to guide the scope and eosbackyard to capture the images (great piece of software). With the scope autoguiding, all I had to do was tell eosbackyard how many images I wanted, duration, and iso and I headed inside to wait it out. 2 hours later all the images were captured and only the processing challenge remained (which I still have much to learn / very different in astro)!

Stacked in DeepSkyStacker, stretched in Photoshop CS6, finished with Picasa.
This is an experiment in stacking. It consists of 3 images (ISO3200, f2.8, 25 seconds), three dark frames and 3 bias frames. The idea is to boost the signal to noise ratio to bring out the faintest stars. In this case, the Milky Way itself. This is the equivalent of an exposure of 1 min and 15 seconds.
Shot using self-modded full spectrum Nikon D5100 through Orion ED80 and CCDT67 reducer, on iOptron iEQ30 Pro mount. Used the Improved DGM NPB filter by Omega Optical along with the UV/IR cut filter by Optolong. Guided and dithered using Metaguide. Stacked in DeepSkyStacker, processed in StarTools.

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour,
That's orbiting at nineteen miles a second, so it's reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the 'Milky Way'.
Our galaxy itself contains a hundred billion stars.
It's a hundred thousand light years side to side.
It bulges in the middle, sixteen thousand light years thick,
But out by us, it's just three thousand light years wide.
We're thirty thousand light years from galactic central point.
We go 'round every two hundred million years,
And our galaxy is only one of millions of billions
In this amazing and expanding universe.
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute, and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth.
17 photos at 18mm, F/3.5, ISO 1600, 2 minutes each. Also 3 darks, combined and whatnot in DeepSkyStacker.
The galactic center is off towards the right. As you look from right to left, we're looking through less and less of the disk of the Milky Way. I managed to catch the entire constellation Cygnus (The Swan) in this image. The stars make up an image that is supposed to be a swan in flight, headed south (to the right in this image). It's actually much easier to see in the sky than in the picture. I highlighted the stars with flickr notes. Also easily visible even in the shrunk down image is the coathanger, one of the coolest asterisms in the sky. :-)
The constellations Sagitta (the arrow shot by the centaur Sagittarius) and Vulpecula (The Fox) are also in this image, between Albireo and Altair. Delphinus (The Dolphin) is also visible towards the bottom right. Although Delphinus is made up of somewhat faint stars, it's small and pretty easy to pick out at night.

M42 - Orion Nebula: Canon 70D, EF 300mm f/4L IS USM, about 9 min (15 x 35s with DeepSkyStacker), ISO 640, iOptron SkyTracker
Used my Lumix GH2 and Canon 50mm lenses with a proper adapter to capture this composition of 20 shots featuring Jupiter in the left and M44 on the right. The Beehive Cluster, also known as Praesepe (Latin for "manger"), M44, NGC 2632, or Cr 189, is an open cluster in the constellation Cancer. It is one of the nearest open clusters to the Solar System, and it contains a larger star population than most other nearby clusters.
I used DeepSkyStacker to stack the 20 pictures each with a 10s exposure, along with 50 bias frames and 20 dark frames.
I've tuned up saturation to bring out colors, that's all i did in post. No colors were added.

This is my attempt at astrophotography with Sagittarius, the milky way, globular clusters and Jupiter. After many difficult adventures and frustrating attempts I found that this is actually easy, go figure. This was taken with a Canon SX100 IS on a $9 walmart tripod. Camera settings in manual mode: ISO1600, F2.8, Shutter speed 15 seconds, Manual Focus to infinity (or as far out as you can get it), and Self-Timer 2-seconds (to get rid of shakes when shooting begins). Post processing was done with DeepSkyStacker (awesome free program) . Stacked 21 Lights, 10 Bias, 10 Darks. After stacking the pictures it looked like I messed things up (very bright image/washed out, the saved image on desktop looked okay) but I took the image to Adobe Creative Suite 2 (not free, but you'd be amazed at who around you may have a copy, so ask around). In CS2 I changed the contrast slider button, the brightness, thought wow, lets move the red and blue slider button too, lol and saved it. I found that DeepSkyStacker did VERY well and that the image was not messed up, I'm not sure why. Please Please ask questions or make comments. I want astrophotography to be enjoyed by all and it almost destroyed me, till again I found out how easy it is. Thanks to my twin brother who helped encourage me through this, and Skype for letting us exchange photos.
...and an Iridium flare (Iridium 70) and the ATV, a.k.a. Jules Verne. And a couple of airplanes. The ISS was a bright -2.2, the Iridium -2.0 and the ATV was -0.7. The ISS is the bright trail in the centre of the image. The Iridium flare is angled across the ISS just left of centre. The ATV is in a higher altitude as it crosses into the Summer Triangle mid-way between Vega and Altair. This is a stacked image comprising three 3 minute exposures covering a 15 minute period from 8:27 PM EDT and 8:42 PM EDT. When I checked Heavens Above earlier this week I noticed that these three satellites would be in the same area of the sky during this time and I made plans to create this shot. Pretty cool. If I could have done this again I would have upped the ISO to 800. Hindsight is 20/20. The order of appearance: the ISS was captured in the first exposure covering the last 3 minutes of its flight; the Iridium flare appeared about a minute after the ISS disappeared during the second exposure; and the ATV during the 3 minutes of the last exposure. There was a 3 minute gap between the second and third exposures because I didn't use that exposure in the final image.

...and my sincere "thank you and farewell" to .tiff intermediates.
It appeared that I'm not the only one who experience misunderstanding between Canon 60D and DeepSkyStacker. And while the fix is (hopefully) on the way, I tried to walk around the problem by converting .cr2 RAWs into Adobe DNG. Success! It will not make my images any better, but it allows me to "bake" them faster :)
The only downside of this processing pipeline is that now I need real flat-field images. My trick with blurring the light frames works no more.

Processing: images were converted into .DNG format RAWs and stacked in DSS using AAWA method. Final touches in Photoshop.
Note: faster, much faster than with .TIFF. Plus no pain of choosing between linear and sigmoid contrast and no color shifts in resulting image - grey is now grey.
And I have started to collect a library of master offsets/bias frames - will also speed up the further processing.

After I have spent hours to watch the starry sky, I tried to realize a image of our nearest neighbor galaxy : Andromeda M31.
Wihtout using a tracking mount, I took 64 images (+ 20 darks) that I superimposed with DeepSkyStacker software.
In order to improve the clarity of the photograph, I used lightroom. But the focus is not perfect unfortunately...

Finally I got time to take enough pictures after all testing. And this time focus was quite good.
I found a very dark place, where it is good to photograpg and it is only 15 min drive away. (In the middle of 2 cities, other one is quite small, so there is very little light polluting).

Memories:After an imaging run on the Jellyfish nebula came to a close with low altitude I was left with no more narrowband targets left to image. Decided to image the full Moon with narrowband, mapping (SII) to Red, (OIII) to Blue and 50% both (SII) and (OIII) to create a synthetic Green as no RGB filters in my filterwheel.

Getting a little late in the year for this target now, but after five or so clear nights on the bounce, with night time temperatures hovering around 18° C (not good for the sensor!), the transparency was getting a little suspect, so I left off until last night when I noticed an improvement. Got started a little late and, desperate for something to point at, I picked good ol' Cygnus. Just managed 19 subs before it was too low in the west. There was some pronounced horizontal banding in this that I (or more precisely, Noel's tools) struggled with, so a little blotchy in places, but overall I'm pleased considering the low number of subs.

The last time I did this I wasn't equipped with my neodymium filter, so I thought I'd give it another go before it disappeared for the year. With the 70mm widefield I did recently this area leapt off the laptop at me, so I had high hopes for this, but it didn't really happen. Still, it's only 1hr 27mins, and there was a fat moon up there for the latter part of the session, so on the whole I'm quite pleased. No star reduction used in this I'm happy to say. I can do better with this area, but I'll leave it until next year now. Or I may not :)
