NGC 1955, 1968, and 1974 (aka NGC 1991) (2018)

This data was gathered by Martin Pugh in Australia in 2018.  (I've taken my time with it.)  The scope was a 12" RCOS in an observatory in New South Wales.  It is 12 hours of Ha and O3, combined.  The NGC numbers refer to three clusters of stars beginning lower left and proceeding up and to the right, mixed in with three clumps of nebulosity.
