IC 289
IC 289 is a planetary nebula in the constellation Cassiopeia〔(IC 289 )〕 which looks pretty and small with aperture instruments. This nebula was discovered by Lewis Swift in early September 1888. It can be easily recognized because it just lies down to the 10 magnitude star BD +60° 0631. N.J. Martin described IC 289 as, “A nice, faint round planet like planetary nebula. The uniform oval disc shows some irregularity in brightness but is not obviously brighter at the edge.” ==References==
