Light Pollution is Ruining Our Night Sky

Light Pollution is Ruining Our Night Sky

Have you ever looked at a brightly lit building or street light in your neighborhood and thought it was excessive? You know, light shining in all directions or perhaps in your bedroom window, rather than only lighting up the intended area.

Despite it’s size, the Triangulum Galaxy appears much dimmer than M31 – The Andromeda…

Astrophotography from a Light Polluted Backyard

Backyard Astrophotography Summer would not be complete without spending a night enjoying the dazzling beauty that is the constellation Sagittarius. The “teapot” asterism just clears my fence to the south of my backyard in central St. Catharines. From my latitude, August is my last chance to image the many star clusters and nebulae that populate…
