Welcome to my digital astrophotography gallery!

I took these astrophotos with the following equipment:

    --- Canon 40D DSLR camera

    --- Tamron 300mm f/2.8 telephoto lens

    --- Canon 100mm f/2.0 telephoto lens

Except for the Mercury Transit, the Partial Solar Eclipse, and the 2014 Lunar Eclipse, all of these were taken with the lens and camera mounted on a Super Polaris equatorial mount, with its axis of rotation pointed at the north pole of the sky.  The mount is equipped with an electrically-driven clock drive, whose purpose is to automatically track the stars in the sky, thus compensating for the Earth's rotation. This prevents the "trailing" of the stars on such images.

Most of these images were taken from Spectacle Lake Lodge near Barry's Bay, Ontario, Canada.  I took the Lunar Eclipse and Mercury Transit images in Burlington, Ontario.  The Partial Solar Eclipse images were taken in Hamilton, Ontario.

Many of these images are composite ("stacked") images, combined into single images using Deep Sky Stacker.  Most are full-frame, but some are cropped and magnified.

Images are listed mostly in reverse chronological order.
