Hi Chris,
Some bright planetary nebulae you could hunt down at this time of year are the Ring Nebula, Dumbbell Nebula, Blue Planetary and Saturn Nebula.
How much skyglow do you have? Larger planetary nebulae will have a lower surface brightness for a given magnitude.
Smaller ones such as the Blue Planetary have a higher surface brightness for the same magnitude.
Finder charts for each of these are in my
Galaxy and Planetary Supplement.
