NGC 7789 “Caroline’s Rose”

Moira’s wonderful talk last night on the constellations around Cassiopeia made me look back into my archive for images.  I have reworked this one today – a September 2014 capture of NGC 7789,  an open cluster in Cassiopeia known as “Caroline’s Rose”.  It was discovered in 1783 by Caroline Herschel and catalogued by her brother William.
