AMcD Posted January 1, 2022 Share Posted January 1, 2022 (edited) This image of part of the region around Sadr in Cygnus comprises 16 hours of 300 sec integrations taken with a QHY8 OSC and an Optolong L-Extreme filter under Bortle 5 skies, using a TS 152 achromatic refractor mounted on a Losmandy G11. Acquired using SGPro and guided with PHD2. It was my intention to gather 24 hours of data on this target but that will now have to wait until next winter as Cygnus departs the zenith.
