Photo Spotlight   Image posted 3.18.2017

The planet Venus was less than two weeks from inferior conjunction (March 25, 2017, at 6:17 am EDT) when this picture of the 6.3% illuminated crescent was captured by Joe Stieber at 7:45 pm EDT on March  12, 2017, from Maple Shade, NJ. Taken with a Canon 7D Mk II digital SLR camera and a Canon 400 mm f/5.6L telephoto lens (on a fixed tripod), plus a 1.4x Kenko teleconvertor, for an effective focal length of 560 mm, then cropped to a little less than 20% of the original dimension yielding a field about 0.36 wide x 0.27 high. This single frame was exposed 1/8000 second at f/8, ISO 1600 (about one-third stop less than the "sunny sixteen rule" for earthbound subjects). In the days near inferior conjunction, Venus will have an ecliptic latitude of more than +8, so if the weather cooperates and you have a site with low horizons, it should be visible after sunset then before sunrise the following morning (optical aid may help to spot it). During the day of inferior conjunction, it should also be visible in the daytime (probably requiring optical aid). Be certain to block the sun behind a structure if you look! Even with ordinary binoculars, a slim crescent should be visible.
