Ok...
Using astrobyte free software I have generated a list of all the PN brighter than mag 12.6... which is around 150 PN. I am a relative newbie to PN (always been more of a globular person... not literally) and so far have observed 22 different PN.
17 of these are on the list, while 5 are mag 13 or 14. So... I am going to try to observe as many of the list of 150 as possible from a southern sky in town. Wish me luck!! I am armed with my new OIII filter at least...
