I will combine the 5 different types at the end.
I have left the hard ones till last, they will take some time.
OC are difficult to do because some of the bright ones are boring.
BN are very difficult because there are no magnitudes for most of them.
I always look forward to your list's Glen I didn't realise M27 is the second nearest or the second biggest planetery. I would have to agree with it being the brightest, even an 80mm shows this object well. Apparently under dark skies M27 is visable with out optical aid and I have also heard NGC7293 is too?
