Photo of the Week for February 23, 2018

Winter nights can be discouragingly chilly—especially in Canada. Thankfully, there are plenty of celestial attractions to make braving the elements worthwhile. The bright constellation Orion is home to several of the best known deep-sky treasures, including the magnificent Orion Nebula (M42) and the visually elusive, but photographically striking, Horsehead Nebula (B33). Both objects are nicely framed in this 6-degree-wide image by Quebec imager, Sam Berrada.

Sam captured this Orion vista from his observatory in Val-des-Lacs, Quebec, with a modified Canon EOS 6D DSLR camera and a Borg 90FL refractor telescope, working at f/4. The final photo combines 25, 4-minute exposures taken at ISO 1250.
