The images comprising this were taken through drifting, thin cloud - of course, while setting up and locating the (dim) subject, the sky had been perfectly clear! The stars are not as sharp as I'd like, due to various factors. Still, I was pleased with the result, given the conditions.

This Image has been made by using DeepSkyStacker to stack 126 frames captured earlier today of (most of!) the Andromeda galaxy (M31) + M32. A cannon EOS60D was used (15s; exp at ISO 1600) mounted at prime focus onto a Skywatcher 200 reflector.
A star-forming region 5000 light-years from Earth and measuring 130 light-years across. The central stars are emitting radiation and stellar winds, carving out large areas within the nebula.

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.

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.

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.

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!)

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.

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. :)

242 light frames were stacked in DeepSkyStacker with 262 dark frames, 120 bias frames, 95 flat frames and 95 dark flat frames. The resulting stacked TIF image was further processed in PixInsight. Workflow included dynamic crop, background extraction, photometric color calibration, noise reduction with TGV Denoise and Multiscale Median Transform, non-linear stretch, colour saturation, removed magenta colour around stars, star reduction, dark structure enhancement, and further background smoothing with Multiscale Linear Transform.

I stacked three 30 second exposures to enhance the Zodiacal light, Comet Holmes, and the Andromeda Galaxy.
OTA: GSO 6" F/5 newtonian reflector
Starizona Nexus 0.75x coma corrector (for f/3.75)
Camera: ZWO ASI1600MM
Exposure: Ha 8x10min, O3 10x10min, S2 18x10min
Mount: CEM70G
Captured with SGP
Registered and stacked with DeepSkyStacker
Photographed from Round Rock TX
Manually guided for 12 x 7-minute exposures at ISO 1600, f/6.25. Modified EOS 600D & Sky-Watcher ED80 refractor, piggybacked on a Celestron C8 telescope for guiding.
Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves & colour-balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.
Lens: Nikon 180mm ED AI-s f/2.8, shot at f/2.8
Camera: Canon 6D (unmodified)
Exposure: 23x4min iso800
Filter: None
Mount: Celestron CG5-ASGT
Captured with BackyardEOS
Registered and stacked with DeepSkyStacker
Photographed from Marathon Motel, in Marathon TX
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.
First night out with the Explore Scientific ED102CF Telescope. 60x60" exposures shot with a Nikon D7200 on an unguided Celestron AVX Mount. Stacked with DeepSkyStacker and processed in Lightroom/Photoshop.
The little constellation Triangulum... the triangular-looking triangle at the bottom... shares its space with the open star cluster NGC 752 to the left and M33, the Triangulum Galaxy.
Captured under the dark sky of Killarney Provincial Park, Ontario.
...still raining, and a reprocess of a reprocess! Learning all the time. :) Horsehead and Flame Nebulae in Orion. 8 January 2011
From the original image:
200p, EQ5 unguided
Nikon D70 full spectrum prime focus
20 x 60 second subs iso 1600
20 darks
20 bias
10 flats
Stacked in DSS processed in CS5
Gonna leave this one alone now! :)

Also appearing, higher in the sky, is Comet Lovejoy (C/2013 R1), currently cruising through southern Ursa Major. Stack of 20 frames of 6 seconds each.
522 1-s exposures, ISO 6400, f/5.6, 300 mm. Photographed from an urban location -- lights from a million people.
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).

Running Man Nebula, M43 and M42 in constellation Orion. Distance:1300l.y.
Taken from suburban Sydney backyard on 17/10/2009
Modified Canon EOS 400D, Orion ED80 (FL600mm) at prime focus. IDAS LPS filter
EQ5 mount autoguided by PhD
ISO800 3 X 4.5min subs stacked in DeepSkyStacker with darks.
A much improved effort from the previous :

I have no clue what I'm doing. Stacked 10 Light frames of f/1.8, 5 sec., ISO-400, 0 step, 28 mm in DeepSkyStacker 3.3.2, converted to 8 bit RGB Photoshop file, edited in Lr5.
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).
