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...
Tehnical datas :

50 mm lens

64 x 8 s = 8.5 minutes of exposure
ISO3200

Although this may, on the face of it, appear to have lost some detail, I'm happier with this. I think the previous version was a little overcooked, and I prefer the stars in this one as well. Slightly wider crop. If I get the opportunity I'd like to give this more time, but when using a zoom lens, all the time has to be in one session as any slight variation in focal length will cause DSS to throw a wobbler. :)

The Sunflower Galaxy, M63 aka NGC 5055 is in the constellation Canes Venatici. It's about 37 million light years away and is part of the M51 Group which, not surprisingly, includes M51.
This was an absolute pig to process. It's not hugely bright and needs a lot more than the 50 minutes I was able to give it. Still - I can cross it off the list now! :)

I could have produced a much cleaner image by dropping the ISO a stop and gathering an hour of light rather than 16 minutes, but I wanted to see how the D610 would perform when pushed. Pretty well it seems. The grainy looking grey stuff around the edges is dust that's just on the verge of visibility with such a short exposure.
Also the composition isn't that great.

After 20 frames I was starting to lose the feeling in my fingers, at which point I figured it was a good time to stop. So, unless it repeats its 1892 behaviour and undergoes a second outburst sometime in January, this will probably be the last image I'll post of Comet Holmes.
Two naked-eye comets, a total lunar eclipse, and a daylight lunar occultation of Venus: 2007 has been a pretty good year for astronomy!
Best viewed large.
The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter.

I got lucky when I wanted to shoot a long exposure of the milky way in Senj, Croatia: there were divers in the water with lights, adding an interesting extra element to the photo.
Shot with D7100, Sigma 17-50mm @ 22mm, F2.8.
ISO 1600, 15s.
I used Deep Sky Stacker to stack 18 light frames and 18 dark frames. Once with alignment for the stars (sigma-delta stacking) and once without alignment for the foreground (averaging).
The water with divers is from a single shot, because they moved from shot to shot.
Composed the final shot from these 3 images.

Never throw your old photos away, you can always get more out of them later.
The same 20 frames as before, just different tweaks in DeepSkyStacker. Still very noisy, guess I'll add more lights when it returns in winter.

NGC7000, the North America Nebula, is located in the constellation of Cygnus. It is a very large area of emission nebula -- a cloud of superheated gas and dust -- extending some 2.5 degrees to the east of Deneb. It was discovered in the early 1890s during experiments in wide field astrophotography.
This image was taken through a narrowband (13nm) hydrogen-alpha filter. Details for the astro-geeks:

Picture I am finding post processing of astro images very hit and miss, and quite difficult, had another go at this one from the same stack file as previous, and tried very hard not to blow out the highlights, and this is the result, I think to an exstent astro post is very much to personal taste.

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.saved with settings embedded.

Been waiting to have a crack at this - couldn't wait for the moon to go away :) Three quarters of these subs were taken with a fat moon looking on, so I'm quite pleased really.
Only got half the loop in here (gets a bit faint out to the right), and I did have room on the left for Sharpless 264, but that didn't put in an appearance at all - so I cropped it!
This is the first iteration, others may follow. Or I may wait until the moon has gone and have a crack at 4 minute subs - difficult unguided on the equator though.
Don't ask me where the spikes came from - I haven't a clue. :)

There are no fewer than four "bright" comets visible in the pre-dawn sky from northern latitudes right now. The two brightest are ISON and Lovejoy. Lovejoy is the one most well-placed for admiring from my location, the others being too close to the sun to afford much of a photographic opportunity. Lovejoy and ISON both have a coma that is glowing bright green due to the formation of poisonous cyanogen gas. The "dirty snowball" is getting brighter as it approaches the sun and the increased heat sublimates the ice producing more gas. The tail is rather dim now (best seen in a dark room with averted vision) but is expected to become more prominent as it nears the sun. Lovejoy swings around the sun in early December so here is hoping it survives its scorching. If it does survive, it will be visible through most of 2014 albeit becoming dimmer with time. This is a stack of 33 x 10 second frames stacked in DeepSkyStacker. Prince George, BC, Nov 16, 2013.
This is old data but reprocessed using separate layers for DSO and stars. A definite improvement I think, considering it's just 16 minutes. This is back in the day (all of 8 months ago) when I couldn't get longer than 60 second subs no matter how hard I tried. Having said that, I haven't pointed my kit at the equator for a while, so we'll see! Looking forward to having another crack at this this year. :)
