Probably - give it the 'blink' test. Look directly at it, then away, then back at it. If it appears to 'blink' on and off, that's it. A lot of planetaries are like this with low surface brightness and they look best in averted vision.
I was going to add that the Blue Planetary is a bit notorious for being hard to find, as it is very star-like.
For others to try, the Ring Nebula in Lyra is fairly bright, and I usually find the Dumbell large and easy. The Ghost of Jupiter in Hydra is a good one too, but it might be too late in the year for it, its a good Autumn object.
