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!)

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.

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.

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 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).

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!

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.

This image of the Ring Nebula (M57) has been cropped from a stacked data-set of images taken last night using a Canon EOS 60D mounted onto a Skywatcher 200 reflector.
A bit more software experimenting, this time using Deepskystacker.
This works in a different way to Starstax which layers up multiple frames for startrails. This one aligns the stars, making them brighter, by adding one on top of the other.
A side effect of this action is that it loses a lot of the other rubbish that is in the original images like meteors, aircraft, satellites and clouds, Oh and hot pixels from the sensor.
This is a blend of 48 x 20second exposures, then the foreground from one of the original shots blended in, as in the lining up process, fixed land based objects get blurred.
Must find a more interesting sky to experiment with this software some more :)
none of these astro pics could have been possible without Mo. Thanks for helping the noobie Mo.

... until I've overhauled my EQ5, sometime when. I need more data and can't get it with 30 second exposures. Hopefully the overhaul will enable me to hit an unthinkable 90 seconds!
This one's better framed than my previous efforts, and the running man is just about visible, which is nice. Pleased considering there was a big moon up there.

I`ve been waiting for a clear moonless sky for many months now, just so I could give my latest filter a proper test. I purchased a Hutech IDAS LPS-V4 Nebula filter earlier this year to see if a One Shot Color CCD could do a decent job of recording Ha and OIII at the same time. The theory was that as the OIII wavelength falls almost exactly half way between the green and blue pixels (at a lower sensitivity though), I should get be able to stack the 2 green channels and the blue channel all as one large stack, and therefore grab 3 times the exposure of OIII compared to the single red pixel collection Ha data. Well, it kind of worked. The Ha data is nearly sharp as previous sessions with a 13nm Ha filter, and certainly usable, but not as good as my current Baader 7nm Ha filter. The OIII data (even after stacking) seems a bit washed out, and I believe this is because of the wide passband around the OIII wavelength (50nm wide at the very top of the peak), allowing in additional noise that a real narrowband filter would
block.
Even so, as an Ha/OIII/OIII combined image, taken from a moderately light polluted area in one single session without having to change filters, I would say it was worth the time to do this test. The real question will be what happens to the OIII data when the moon fills the skies, as OIII tends to be washed out from moonglow far more than Ha data.

This is one way that you can setup the equipment that I have for sale. I prefered setting up the guidescope and main scope in a side by side configuration. If you wanted to you could attach the guidescope directly to the telescope. All required cables are included.
To take and process pictures you will need the following:
BackyardEOS - purchase online $24
Deepskystacker - free download
PHD - free download

Most important lesson learned: tripod stability is everything. I took 35 mins of exposures, and lost 12 to shake, likely from passing cars. Next time, I go further from the road, stabilize the tripod better, and pick sturdier ground.
