Photo of the Week for September 16, 2016
Each summer produces a bountiful harvest of new images of the season’s deep-sky wonders. The swath of Milky Way that runs northward from Sagittarius, through Aquila, Cygnus and on into Cassiopeia, is fertile ground for observers and imagers alike. One object that makes its way onto many hit lists is the North America Nebula, situated near the bright star Deneb, in Cygnus. This photo by Roman Kulesza shows the region beautifully. The North America Nebula itself is catalogued as NGC7000, while the prominent patch of Nebulosity to its right is IC5070 (also known as the Pelican Nebula) and the faint patches below form IC5068. The brightest star in the image—near the bottom of the frame—is 4th magnitude Nu (ν) Cygni.
Roman captured this exquisite view from the township of Tiny, Ontario, (40km north of Barrie) with a modified Canon EOS Rebel XSi DSLR camera fitted with a Canon EF 200mm f/2.8L II USM lens, working at f/4. The final image is a stack of 36, 5-minute exposures at ISO 800.
