Asteroid 2012 QG42 getting closer – 10 Sept. 2012

Asteroid 2012 QG42 (10 Sept. 2012)

Asteroid 2012 QG42 (10 Sept. 2012)

On Sept. 2012, while waiting for its close approach, the Virtual Telescope Planewave 17″ unit was slewed to image asteroid 2012 QG42 again. This time, the Paramount ME robotic mount was left tracking at the sidereal rate, to register the asteroid as a trail.

This is a 300 seconds exposure, unguided: the trail is about 100 arcseconds long!

Don’t miss our live observing session of this asteroid next 13 Sept.!
