Today is the last day of my vacation. This is the place that I spent a few days and let me tell you, the stars are just amazingly beautiful up there in the mountains.
Photo info: several shots stacked with DSS (DeepSkyStacker - deepskystacker.free.fr/english/index.html only to increase the Signal to Noise Ratio (SNR).
A bit of hot highlights from the bare flash on the cottage at the end of the exposure but this is it ...
M42, The Great Nebula in Orion
Second pass at data from March 21, 2014. M42, 10 minute stack of 20x30" exposures on a Canon 500D through an Orion ED80.
Captured using Backyard EOS, stacked with DeepSkyStacker, post-processed in Pixelmator.
Panasonic Lumix GH2 with Panasonic G Vario 14/43mm 3.5/5.6f. Shot at 14mm and wide open.
Location: Capolago, Ticino, Switzerland.
The bright object at the center of the picture is jupiter!
Tried to capture Jupiter in the night sky. Stacked 32 pictures, each with a 20s exposure at 3.5f with DeepSkyStacker. The purple glue is due to the light pollution from the nearby small town..

Fujifilm X-T10, XF18-55mm F2.8-4.0 @ F5.6 and 55mm, ISO 3200, 10 x 3 min, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing in GIMP, taken Sept. 28.
Cropped quite a bit.
Oct. 2 update: Removed some of the light pollution gradient.
Mar. 7 update: Star reduction.
The comet, currently in Andromeda, was easily visible via 7 x 50 binoculars. However I couldn't image through the 'scope, as the comet is to the West and my view is blocked, so I just used a short telephoto lens on a star tracker, and cropped the result a little. The comet’s tail can be seen faintly in the photo, pointing to the 2 o’clock position. The slight gap in the star trails is due to the sequence of frames being broken by passing cloud.
19 x 30-sec exposures at f/4 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens, on a Vixen Polarie star tracker; frames stacked on the comet (hence the slightly trailed stars) in DeepSkyStacker, with curves adjustment and further noise reduction in post-processing.
25x60s at iso 400.
150mm (750mm FL) F5 Newtonian with GSO coma corrector.
First try with autoguiding using PHD2. Unfortunately the 3D printed guidescope mount was not nearly robust enough. 2/3 of the exposures were thrown out.
Stacked with DeepSkyStacker and post processed in Photoshop.
Unfortunately a large number of Geo satellites were present in the view and created streaks.
Stacked in DeepSkyStacker and processed in PixInsight, Aperture and Noise Ninja.
Approx 10x60s subs @6400 with flats and darks, through a ED80 @ f/7.5.
72ED apo with SX Trius 694/Ha filter and field flattener piggybacked to C9.25 on a CEM60. Eight 900 second subframes stacked and dark frame subtracted in Deepskystacker and processed in Photoshop CS2. Autoguiding through 9.25 with QHY5L-II colour camera and 0.5x reducer.

Canon EF 50mm lens (MK I), at f/2.8, ISO 800, three hand-tracked exposures (total exposure time 5m 15s), combined in DeepSkyStacker and processed in Photoshop.
I would have gone deeper, but the clouds rolled in. Still, you can see the beginnings of the dust lanes on the large version, and the two satellite galaxies (annotated).
New set of images for this one. My autoguiding is getting better and better after many frustrating hours tuning the mount. Very happy with the star detail on this one.
Date:12/9/2009
Location:Brisbane Australia
Imaging Camera: Canon 1000D prime focus
Imaging Scope: Mak Cas 127mm
Focal Length: 1500mm F12
Guide Camera: SSAG
Guide Scope: Orion 80mm F5 Refractor
Guided with PHD Guiding
Mount: Celestron EQ5 GT
Exposure: 90 min (15x6min) full colour
Darks: 6x6min
ISO: 800
Processing: DeepSkyStacker, CS3, Noel Carboni's Astronomy Tools
My first ever attempt to take Andromeda aka Messier 31/NGC 224. Hopefully this will be good to compare against when I revisit it in the future. I didn't get as many subs as I wanted because contary to the weather forecast the clear skies didn't last anywhere near enough.
Used Sky Safari for my location settings and the talking clock to get the exact time.
2 star alignment with Vega and Capella then slewed straight to Andromeda with no need for adjustment.
(Why cant it always be this simple!)
Nikon D3100 connected to the mount and using a 55-300mm lens .
Yongnuo MC-36R/N3 Wireless Timer Remote.
19 30 second frames (9 1/2 Minutes).
ISO 800, f/5.6, WB Incandescent.
Lens focal length set at 300mm.
Stacked in Deep Sky Stacker with darks, flats and bias..
Processed in Adobe Photoshop Lightroom.
Recommended settings in DSS. Stretched the contrast and clarity in Lightroom.
Taken in Stretford, Manchester on the 31st August 2013.
I've reprocessed this a few times but didn't want to loose this original pic so have posted the updated version here and kept this for my own record.
Just pointed the camera straight up to the coreof the Galaxy. I took 5 photos with DNR on. Using Deepskystacker I stacked them all together then edited the colours and claryity in Lightroom. First time using DeepSkyStacker and I know how to improve for next time. Mainly take more shots! Impressed with my first result anyhow. Just need some interested foregrounds to find!
Nice, bright star cluster in constellation Cancer. This cluster have fallen into the sweet spot of my optics, so the halos around bright stars are at least center-symmetrical and not comet-shaped. Yes! This one turns out at steady 3 out of possible 5.
This shot and this share the same effective resolution so the apparent sizes can be compared. This only applies to "original" size of the images. M67 is tiny compared to Praesepe/Beehive. And has only 7,5m against 4m of the Beehive.
Aquisition time: 13.04.2013 around 23:45:00 MSK (GMT+4).
Equipment:
Canon EF 70-200 f/2.8L lens + Canon EF 2x III extender on EOS 60D mounted on Celestron CG-4 GEM (German equatorial mount) with RA drive.
Aperture 71 mm
Focal length 400 mm
Tv = 30 seconds
Av = f/5,6
ISO 800
Exposures: 85 + 12 dark frames
Processing: contrast was set to "linear" and vingetting was corrected with Canon DPP, 16 bit TIFFs were stacked in DeepSkyStacker, contrast'n'colors adjusted in Photoshop. Image scaled down 50% (cheat!).
Notes: this time I have recorded the steps of contrast adjustment. I'll better have bluish sky than reddish.
Just messing about with some old data now that I've learnt to use GradientXterminator correctly. :)

Same picture as before but used a beta version of DeepSkyStacker that works with my Sony RAW files. Previous pic was with jpeg stacks, light frames only. This one is with the RAW files and 12 bias, 12 flats, and 12 darks. Really makes a difference as far as stretching the image, reducing noise, and bringing out more detail.
Taken with C8-SGT w/ f/6.3 focal reducer.

A wide-field shot of the Ring Nebula (M57) in the constellation Lyra taken with a Nikon D5100 DSLR using a lens of only 100mm focal length. 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).
This is a stack of eleven images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). The faintest stars recorded in this photo range down to approximately magnitude 13.5 (see image notes which identify a few of the brighter stars, north is off to the right).
Captured on October 17, 2011 between 8:03PM and 8:23PM PDT under fairly bright, hazy, light-polluted skies with a Nikon D5100 DSLR (ISO 3200, 25 second exposure x 11) and a 70mm-300mm AF-S G Zoom Nikkor lens at its 100mm f/5.6 position. Image stack created with DeepSkyStacker using eleven image frames combined with eight dark frames (no flats or bias).

While I was about it thought I'd have another crack at this. Not quite as contrived as my previous version (which was hugely contrived ;) ). This is full frame, more or less.
Nikon D70 modded, 55-200 Nikkor at 175mm, f6.3, 1600iso, Baader Neodymium filter.
20 x 4 min and 20 x 5 min subs for a total of 3 hours, unguided EQ5
Darks, flats and bias
Stacked and processed in DSS and CS5, with a little help from Noel's tools.
Celestron CGEM 1100HD with Canon 60Da. ISO 800 with 10 minute exposure. Dark frames and flats were collected after session. Used Celestron's off-axis guider and Orion's 12.5mm illuminated reticle eyepeice for manual tracking. Stack of 19 shots using DeepSkyStacker with GIMP for post processing (mostly tone-down the stars).
Like the dust lane that surrounds this galaxy. It is about 30 million light-years away and only 1/3 as wide as the moon (relatively speaking).

It's often concerned me that my stars always seem to be devoid of colour, so I thought I'd make a small change to my processing steps and came up with this. The original is here. I'd really appreciate some feedback on this because I've been staring at this for hours and my eyes have gone funny. There's certainly more colour in it (there's very little in the original), but I'm not sure if it's overdone or a little too forced. There seem to be an awful lot of blue stars about!

Unmodified Sony a7R and Astro-Tech AT65EDQ 65mm f/6.5 refractor mounted on a Losmandy G11 mount. 20 x 10 minute sub-frames, 5 averaged darks processed with DeepSkyStacker.
A wide-field view of the Triangulum Galaxy in the constellation of the same name captured in a stack of fifty images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). The Triangulum Galaxy is generally consider to be the most distant object that can be seen with the naked eye (it is smaller, dimmer, and more distant than the Andromeda Galaxy).
This is my first serious attempt to photograph M33 and although this image has some problems it actually turned out better than I expected (given that I'm not using a telescope and considering the rather poor conditions from my front driveway -- pretty serious light pollution since I live very close to the center of a large metropolitan area). I can just make out the spiral arms on the galaxy but the short exposure and "push" processing has drained all of the color from the now-bloated stars.
In the image notes I've identified a small object that may be NGC 604 (a very large nebula and star forming region in the Triangulum galaxy -- NGC 604 is perhaps a hundred times the size of the Milky Way's Orion nebula).
In any case, this image is best viewed in the Flickr light box (press the "L" key to toggle the light box or click the following link):
Captured on December 22, 2011 between the hours of 8:09PM and 8:44PM PST with a Nikon D5100 DSLR (ISO 4000, 25 second exposure x 50) and a 105mm AI-S 1:2.5 Nikkor lens set to aperture f/4. Image stack created with DeepSkyStacker using 50 image frames combined with 48 dark frames (no flats or bias).

This is better I think. Less forced than the original (which has been relegated to my "Not good Astro!" set!). Better definition in the dust lanes. I'll open the lens up next time, and equip myself with an LP filter, which is the reason why stars are a little lacking in the bottom right hand corner.
