Wide-Field Cameras In The High Arctic


Located within 10 degrees of the North Pole, northern Ellesmere Island in the High Canadian Arctic offers continuous darkness in the winter months. The lack of a day/night cycle greatly enhances the detection efficiency of planetary transit surveys and other time domain astronomy programs.

We deployed two wide-field cameras at 80 degrees N, near Eureka, Nunavut, for an observing campaign in February 2012. The camera systems were based on commercial f/1.2 lenses with 85mm and 50mm focal lengths, and they continuously imaged 504 and 1,295 square degrees respectively. Together, the cameras took over 44,000 images and produced precision light curves for approximately 70,000 stars.
