North America and Pelican Nebulae Super Widefield, 2021
Cygnus
The North American & Pelican nebulae separated by a dark cloud, 1,500 light years away. I captured their light for 2 hours on 2 bright and short July nights using my fastest astrograph Takahashi FSQ-85ED reduced unguided and a Nikon D810A.
