I found the Blinking Nebula, not sure which NGC# it is 6000 something. It didn't blink, but it was a very bright pretty blue!

The "Blinking" Planetary is NGC 6826, located in Cygnus. It appears as a nearly round fuzzy ball with averted vision in a small scope, but seems to vanish when you look directly at it in a small aperture (hence, its name). In my NexStar 9.25 inch SCT the other night, it appeared as a pretty pale bluish sphere of light about 38 arc seconds across, with a prominent 10th magnitude central star. It takes high power pretty well, so don't be afraid to go high on this one.

It's been my experience that the Blinking Nebula, as well as a number of other planetaires, will also "blink" when observed with larger apertures, such as the ASH 17" f/15 classical Cassegrain.
