- aka Caroline's Rose Custer - Open Cluster in Cassiopeia

Sh2-151 : Emission Nebula in Cassiopeia
--------------------------------------
From Wikipedia: NGC 7789 (also known as Caroline's
Rose or the White Rose Cluster) is an open
cluster in Cassiopeia that was discovered by Caroline
Herschel in 1783. Her brother William
Herschel included it in his catalog as H VI.30. This cluster
is also known as the "White Rose" Cluster or "Caroline's Rose" Cluster
because when seen visually, the loops of stars and dark lanes look like
the swirling pattern of rose petals as seen from above.
