Matching Telescope Focal Length and Pixels

How to match a telescope to your camera – Design considerations such as focal length, aperture, f/ratio, and pixel size.

A Guide to Beating Light Pollution, Part 1

 I have tried a number of techniques, filters, and processing steps that have allowed me to continue enjoying my passion despite light polluted skies.

A Guide to Beating Light Pollution, Part 2

In Part 2, we’ll look at imaging techniques, camera settings, and software processes that help further mitigate the effects of light pollution on deep-sky images.

Talk – An Introduction to Deep Sky Astrophotography

An introductory talk on astrophotography for the Royal Astronomical Society of Canada (RASC). Some examples, guides, and tips for beginners were discussed along with some questions and answers at the end of the session.

How to Setup an OAG

With long exposure astrophotography, the motion of night sky must be tracked perfectly as the Earth rotates to get sharp images.

While this seems simple in theory, in practice, small discrepancies can spoil the perfect tracking required. These are corrected by “guiding” the mount.
