Title: Cygnus - Deneb and Sadr and lots of objects
Post by: The Thing on Jul 25, 2020, 11:43:32
This is about half of Cygnus with Deneb right and down from centre, North American and Pelican nebulae below that and Sadr up and left with all its bits and bobs. The Crescent is evident near the top edge at the left. I did an annotated version but there are zillions of NGCs, LBNs, LDNs, SH2s, DOs, IC this that and the others lurking in the image.
Taken with an Pentax 35-105mm f4 zoom at 70mm f5.6 on a StarAdventurer. Since I was at home I could plug in the camera and use the cooler. 58x60s No calibration frames, Gain 120, Offset 4, Temp -15C.
