Photo of the Week for April 8, 2016
Currently making its way through the constellation Ophiuchus is Comet 252P/LINEAR. Under good conditions it can be seen in the predawn sky with ordinary binoculars, appearing as a small fuzzball. Photographer Malcolm Park captured this scene on April 5, 2016, at 5 a.m., EDT, from Bloomfield, Prince Edward County, Ontario, looking south over Lake Ontario. Also shown are two additional solar-system interlopers, Mars and Saturn. Can you identify all three in the photo above? (If not, scroll down for the answer key.)

Malcolm used a Nikon D810A DSLR camera at ISO 3200 and 14-24 f/2.8 zoom lens (set to 24mm and f/4) on a Sky-Watcher Star Adventurer tracking mount for this single, 60-second exposure.
