Astronomer Vance Petriew at the eyepiece of his 20-inch Dobsonian reflector telescope, at the 2012 Saskatchewan Summer Star Party in Cypress Hills, SK. This is a single 20 second exposure with the Canon 5DMkII at ISO 4000, and 24mm Canon L-series lens at f/2. A faint aurora adds the horizon colours. The photo was taken on the occasion of the second return of Comet Petriew 185/P since its discovery 11 years earlier in 2001 at this very same location.

Me aiming the A&M 80mm refractor on the Astro-Tech Voyager mount at the Milky Way with its laser pointer finder showing the way. I am aiming at M11 in Scutum.
