Description

This is a faint, smaller version of the better-known Rosette Nebula.  It is located in Cassiopeia.  We have a rare run of clear moonless nights going this week.  My first attempt aborted the night before last, due to heavy dew triggering my automatic rain closure.  So I re-ran it last night, after turning down the sensitivity of the rain sensor.  It turned out to be worth the effort.
