The Transit Of Venus

by obsidianphotos in Astrophotography

WARNING: NEVER DIRECTLY OBSERVE THE SUN WITH THE NAKED EYE OR THROUGH A TELESCOPE, CAMERA OR OTHER OPTICAL DEVICE UNLESS YOU HAVE A PROPER SOLAR FILTER SECURELY FITTED AND KNOW EXACTLY WHAT YOU ARE DOING.

5th and 6th of June 2012. The planet Venus makes it's way slowly across the face of the sun for the last time this century (as seen from Earth). The next Venus Transit will not occur until December 2117.

I was absolutely blessed with beautiful weather for this event. I was fully prepared to pack up my gear and head off to chase clear skies but two days out from the transit all the weather forecasts pointed to a fine and clear day for my home area. I decided to trust it and I invited family and friends around to witness it with me. Despite many casting doubts over my weather forecast due to the persistent rain in the days leading up to the event, I never backed down and the day dawned with not a cloud in sight. It remained that way until about one hour after the transit had finished when the clouds started to roll back through. In addition to the Coronado solar scope I also had an 8" F/6 Dobsonian Telescope setup with a white light solar filter so that family, friends and I could visually observe the transit at the same time as my camera was doing it's thing on the other scope.

This sequence spans a 6 hour period from second contact (left) at 8:30am (Australian EST) through to third contact (right) at 2:30pm. The shots in between were taken at half hour intervals.
