Here are a couple of sketches I've done... they're originally done with pencil on paper, then "flipped" to give a more realistic appearance.
I've done a bit of astronomical imaging using video cameras and backyard telescopes. All of the images on this page have been taken using a PlanetCam CC video camera from Anirondack Video Astronomy and a 12" Meade LX200 owned by the Winnipeg Centre of the Royal Astronomical Society of Canada.
