| Description | I'm not usually a big "open cluster" fan, but this one is unusually beautiful. Also notable as having been discovered by Caroline Herschel, sister to William, in 1783. Caroline, along with her brother, would have to be counted among the top 50 most influential astronomers of all times. William was the most accomplished telescope builder of his era, allowing him and his sister to discover a remarkable share of the most important DSOs visible from England. Caroline was the notetaker and cataloger who published the listings of the family's observations which morphed into the New General Catalog (i.e. the NGC in NGC 7789). Indeed, of the 7,840 objects in the NGC, Caroline and William discovered at least 2,500 of them. This capture took advantage of SharpCap's color calibration, my new 2600 camera, and some more sophisticated processsing including NoiseXTerminator. |
