Description:
NGC650 and NGC651 are the 2 lobes of the bipolar PN. The PN is also known as
M76 and PK130-10.1
30CM/F:10/SCT
203X - A faint (12m) dumbbell with 2 feild stars lying in a line parallel with
the bipolar axis of the PN. The central star is not visable. The O-III filter
dims the PN too much to improve visibility.
60.9CM/F4.5 Newtonian
124.7X - A very faint outer arc of nebulosity was barely detected with direct
vision. The central star was not seen with either telescope. The bipolar nature
was quite visable in the 60.9CM and also detected in the 30CM instrument.
