Ok, so Venus isn’t an extrasolar planet (exoplanet), but I thought this would be a cool thing to try. A while ago I put together a time-lapse movie of the 2012 Transit of Venus. More recently, during a public talk on exoplanets, I saw a video someone had made to demonstrate the transit method used to detect planets around other stars. The video looked a bit like my time-lapse, except that it was a simulation. I thought, “why not try to get a real light curve from my transit footage?” Continue reading
Venus passed in front of the sun on 6th June 2012, and all the while I was happily photographing it from tropical North Queensland. Here is the time-lapse of all the photos I took throughout the day. The music is by Kevin Macleod – thanks Kevin! Continue reading
If anything shows off the low light capabilities of the 5D Mark III, it’s astrophotography. For me this doesn’t go any deeper than wide angle shots of the night sky, but luckily I got to try out the camera on some really dark nights at Siding Spring Observatory earlier this year. What strikes me about the 5DIII’s high ISO noise performance is how much colour and contrast detail you can retain. Bear in mind all these shots are at f/2.8.. if only I had a 1.4! Continue reading
On 6 June 2012, Venus passed directly between Earth and the Sun. This ‘transit’ won’t happen again until 2117, so I’m happy that I got some photos of it! I was asked to write a few words on my experience for the August 2012 issue of the AAO Observer newsletter, so in lieu of rehashing the same story, here’s what I wrote for the article.
