Shutter:1/12 sec
Camera:Canon EOS 60D

A wonderful sight tonight, as I caught Venus in its last days before the transit, shining as a glistening crescent low in the evening twilight.

Venus was visible to the unaided eye after sunset, but not for long. It set soon after the Sun. But for a short while it put on a beautiful show as a large crescent (large for a planet that is), easily resolvable in binoculars and stunning in a small telescope. One could almost make out, for brief moments, the sight of the backlit atmosphere going all the way around the disk. But I suspect it was more imagination at work than reality shining through.

The inset blows up the boxed area, to reveal the crescent-phased disk of Venus, despite this shot being taken with no more than a 200mm telephoto lens. I used a Canon 60Da camera at ISO 100. A plane is flying just below Venus.

So this was May 30, 6 days before the June 5 transit, with Venus 9.5° east of the Sun. How far up to the Sun can we catch it, before it crosses the Sun on Tuesday?
