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.
Here in UK, summer nights are bright and short so I had to be very quick. For that reason, my FSQ-85ED was equipped with its dedicated reducer making it a f/3.8 astrograph. No guiding was used as the encoders of the CEM25EC mount can handle the 3 mins exposures I used fine.
