NGC7789 by Ron Brecher
One of the finest non-Messier open clusters in the sky is this gem, NGC 7789, located in western Cassiopeia. The grouping was discovered by Caroline Herschel (sister of the famed British astronomer, William Herschel) in the autumn of 1783.
This fine portrait of “Caroline’s Rose” was captured by Guelph, Ontario, astrophotographer Ron Brecher. Ron used a QSI 583wsg camera attached to a 10-inch ASA astrographic reflector working at f/3.6 to acquire the image data. You can see more of his deep-sky photos by visiting his web site.
