North America Nebula (NGC 7000)
This is 1h22m30s of 30s exposures (165x30s) from Friday August 2, and 2h7m of 1 minute exposures (127x1m) from Sunday August 4. The total integration is 3h29m30s.
These were shot through a canon 100-400 f4.5-5.6L ii at f5.6/400mm using a Hoya red intensifier with a Sony A7iii at iso 640. The files were not calibrated, but profile corrections were applied in Lightroom prior to stacking/processing in Pixinsight.
