Planetary Nebulae
Last night I looked at 16 Planetary Nebulae with my 12" Dobsonian and an 8mm eyepiece at 190 times with a 25' field.
The PN were ICs 418 & 2501 and NGCs 1535, 2346, 2392, 2438 in M46, 2440, 2867, 2899, 3132, 3195, 3242, 3699, 3918, 4361 and 5189.
The most difficult PN was I2501 as it is almost stellar. I had to use a UHC filter to confirm it. I418 is also small. N2346 has a bright star in it and also needs a UHC filter. N2867 is small. N2899 and N3699 are large and faint. N3195 is small and faint. The rest are pretty easy to see.
