Photo Spotlight   Image posted 5.09.2021


Club member Joe Stieber captured this image of the inner planets, Venus and Mercury, from Wharton State Forest, NJ, on April 26, 2021. It was taken at 8:07 pm EDT, 19 minutes after sunset when they were 1.6 apart using a Canon EOS RP mirrorless camera and a Tamron 150 to 600 mm F/5-6.3 zoom lens (set to 600 mm focal length) on a fixed tripod. Exposed 1/1000 second at f/6.3, ISO 6400. Mouseover for labels. These two inner planets are becoming a relatively easy target after sunset during May 2021, and on May 12 and 13, will be joined by the young crescent moon as described in Sky & Telescope's Sky at a Glance, May 7 to 15.
