Meanwhile, closer to Earth …

The eyes of stargazers have largely been focused on comet C/2020 F3 (NEOWISE) of late but there are other dazzling sights the cosmos offers; among them is Earth’s Moon.

CAA member Alan Studt has been pursuing a project to photograph — as possible — Moon every day through its cycle of phases. He has captured most phases thus far. At the time of this writing, Luna was in her waning crescent phase with the sliver of lighted disk growing slimmer by the day. The crescent phases offer dramatic views of Moon due to low-angle sunlight casting longer shadows from lunar surface features.

Above is our Moon seen the morning of July 17, 2020, day 27 of the Lunar cycle – 10% illumination – 394,051.09 km away. Studt’s technicals: Four shots stitched, Nikon D850, 4400mm, f/20, ISO 2000, 1/80th sec.

Below is Moon accompanied by planet Venus, accentuated by sunrise-tinted thin clouds. Settings: Nikon D850, 350mm, F/5.6, ISO 250, 1/100th sec.

Venus transits the Pleiades

Once every eight years, as dictated by orbital mechanics, planet Venus crosses the Pleiades star cluster. The star cluster is one of those nearest Earth and easy to spot: to the right and running ahead of the great Orion constellation. It’s an open cluster consisting of about 1,000 gravitationally-bound stars though only a few of them are visible to the unaided eye. Longer camera exposures reveal more and more stars in the group. The before, during, and after-transit conjunction positions of Venus and the Pleiades make for a lovely sight by eye, telescope, and a favorite target for astrophotographers. Shown below are some of the images CAA members have made of the April 2020 Venus/Pleiades combinations.
