My take on the Venus transit
Jun 14, 2012

Transit photos are not breaking news anymore, but I had to finish other photo gigs before processing the photos, taken near Nevada City, California. I got lucky with clouds and managed to get a nearly complete sequence at 15 minute intervals.

Here's the rig I used: a home-built barn door mount to track the sun so I didn't have the repoint the camera for each photo, RRS ball head, E-30 + EC-14 + OM converter + Oly 500 mm mirror lens + Orion solar filter, for effective focal length of 1400 mm at f/11. This photo was taken 3 hours into the transit, when the curved rod has run out of travel and needs to be rewound for another 3 hours of tracking:

This composite was put together with photos taken at 1 hour intervals:

The moment when Venus has just ingressed completely over the solar disk. Sunspots are indistinct because of high haze after the storm.

Two hours and 8 minutes into the transit:

Surprisingly, Venus and sunspots are visible through clouds:

Minutes before sunset, with Venus visible through the trees:
