So I heard Google+ is being shut down, in which case this is my goodbye post. For what it's worth, I liked G+ and made a good many friends from the networks here. It has a lot of promise but didn't quite pivot to where it needed to be. I will refrain for sharing my many opinions on how it could have worked (what's the point?) but suggest to the users of any social network never to rely on it as an archive for your work. I've maintained my own work on deography.com for 14 years (longer than FlickR or Facebook or G+ or any similar service has managed to exist).. and will continue to do so. If you ever want your own website that will never go away until you want it to, reach out to me. I provide hosting and web development, domains and all that good stuff via my company DNA Digital.

I leave you with the Helix Nebula, taken 2 nights ago with the new Celestron 0.7x reducer and Celestron 9.25" Edge HD telescope.

So long G+ and thanks for all the phish.

Looks like YouTube hasn't been sharing my astrophotography videos with G+ for about 5 weeks. Sigh. I have been active in that time! Sorry about the radio silence. Here is today's post about How To Photograph the International Space Station.

Looks like an eyeball right? With the LMC galaxy as the pupil and our Milky Way arching over a local coastal lake system. 5 panel panorama with #canon6dmarkii and #tokina16_28mm :) #astrophotography #canonaustralia #byronbay

I took this image of the weirdest looking galaxy in the sky, NGC 5128 Centaurus A, over 2 nights but honestly didn’t manage to get enough good data to do it justice. Sometimes called the “Hamburger” galaxy, which I think really undersells how amazing this view is, I think it looks like a brilliant candle. It puzzled early astronomers for a long time who couldn’t work out whether it was a nebula or something else. Eventually they realised it was an elliptical galaxy on an angle towards us, and the brilliant and sharp dust lanes hide a black hole spewing radio emissions to either side.

But is it really weird? Or is it just an unparalleled view of a typical elliptical galaxy that happens to be so much closer to us than most galaxies we can see? I think Kanipe & Webb sum it up really well in their latest edition of “Annals of the Deep Sky” saying “We consider this outer system one of astronomy’s most iconic objects, one embodying both astrophysical paradigms and exceptions. We are fortunate, indeed, in having it nearby, close enough to look down it’s throat and into it’s luminous heart.”

Taken at the full 2350mm focal length of my Celestron 9.25″ Edge HD / F10.

45 mins of Mono Lum with QHY9 CCD and 30 mins of Colour RGB with QHY12. The colour didn’t really work out too well shooting so low and early in the evening, but I’m pretty happy with the details!

Oh do I need some sleep. After months of terrible conditions I got 5 nights in a row of near perfect astronomy weather. So here also is this years take on the Tarantula Nebula, resting on the edge of the Large Magellanic Cloud. This massive cascade of nebulosity is different from the ones I usually photograph which are in our galaxy, the Milky Way and so much closer to us. These are nebulas in a far distant galaxy. You can see all the young stars in blue, being spewed out of the red clouds as new star systems are formed in this huge star factory.

For the imaging nerds, this was created with 3 separate image runs over 3 nights. One in mono with no filter (broadband), one in one-shot RGB colour and one in Hydrogen Alpha which is added as a luminosity layer.

105 x 1m Mono
36 x 2m RGB
21 x 2m Ha
Total Integration Time : 3.65 hours
Celestron 11" RASA / CGX Mount / QHY9 CCD / QHY12 CCD

The Christmas Tree Nebula, including the Cone Nebula, vaguely looks like a christmas tree I suppose! It certainly is a colourful cluster (NGC2264) with both reflection and emission showing blue and red clouds respectively. This is taken in broadband mono + one shot RGB over two nights for a true colour / natural view as the human eye would see it - if our human eyes weren't so weak and pitiful. Celestron RASA, QHY9 + QHY12 CCDs, CGX Mount. 20 x 1m mono + 28 x 90s RGB. All us eastern Australians are a little bleary eyed today after several days amazing astrophotography weather with no moon and very clear skies. #astrophotography #celestronrocks

I worked out how to do a blind identification of a UFO! So I scoured my old data for possible suspects and found this guy. Using astrometrica I was able to ID it as asteroid 9199 FO1 (1993) and generate an official observer report. Now I can move onto undesignated objects / recent NEO discoveries. :)
