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...

Total exposure time is 22min. 11 sec.

Stacked in DeepSkyStacker and edited in Phohoshop.

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).

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 :)

There's a full moon tonight so conditions are not ideal, but it was such a clear night I thought I'd try this again.

This is made from stacking around 180 two second exposures (ISO1600), using Deep Sky Stacker. Roughly every 10 shots I put my glove over the lens hood and took a 2sec dark frame.

The extent of the galaxy is much more visible and the dust lanes I thought I could make out in my first attempts are obviously there in this image.

The darker band at the bottom is due to me placing the target at the lower right of the frame at the start so there's progressively less exposure the nearer the edge, because those parts were out of frame for part fo the total exposure.

While Rosalind and I spent a few days in rural NSW, we had clear skies at night and I decided to get a good shot of the Southern Cross (Crux). It's amazing how a photograph can show so many more stars than the eye could see. The stripe of the Milky Way passes right through this photo.

The bright star in the lower left part of the picture is Alpha Centauri, the closest star system to our solar system - a little over 4 light years away.

This was my first real attempt at astrophotography, a subject I learned a lot about while processing this photo. I didn't have a system to track the stars, so I was limited to about 15 second exposures to prevent star trails. I took 8 shots and merged them in DeepSkyStacker to produce this image. I'm looking forward to the next time I'm in a clear, rural area so I can try some more astrophotography.

This is a stack of 8 subs of 300 sec each, using DeepSkyStacker with LogSqRt of luminance stretching. Added Halpha filtered image as Red. Added Televue Nebustar filtered image (Hbeta+Oxygen3 as Blue layer.

Not the first time I've imaged this object this year. Last time I used the C8, so it was good to be able to use exposures half as long this time, but at the expense of coma (distorted stars around the edges). I'm still pleased with the result, which I've processed to emphasise the reddish areas of star formation.

Moon up there, and not a lot of dark, so thought I'd reprocess something, as you do.

More definition and colour in this version I think. Not sure if the colours are correct, but it looks nice!

Deux tentatives réussies de capturer la comète C/2013 R1 Lovejoy. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine. Je tenterai de combiner les 10 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.

Two attemps of capturing Comet C/2013R1 Lovejoy. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, which was that far in the sky (roughly 90°). I will try to stack the 10 good files I made in Deepskystacker or IRIS.

These towering tendrils of cosmic dust and gas sit at the heart of M16, or the Eagle Nebula. The aptly named Pillars of Creation, are part of an active star-forming region within the nebula and hide newborn stars in their wispy columns.
