Hi Rob, I observed Mizar with a 15" reflector last night. There was an 7.9 magnitude star SAO 28748 about one minute southeast of Mizar at 1:28 AM MDT. It forms a triangle with Alcor and Mizar. Since the handle of the Big Dipper rotates the cardinal directions of the star with respect to Mizar also rotates. Perhaps this is the star you saw?

I guess about 1' separation, I put in 9mm EP's (58x) and still there. Swung over to Sirius and no reflection, back to Mizar and I shook the binos and the 'x companion' moved in sync. Other bright stars and no ghost companions. And then the clouds came in. I'll wait a bit and maybe we'll clear, I'll get the 9.25 ready though seeing is about 5 tonite Rob Sent from Rob's iPad

Just imaged Mizar again but this time with the scope and camera rotated 180 degrees.
No sign of anything unusual.
Bummer...

Oh well, it is curious though that scopes and binos see the same reflection. I'll set up the 9.25 still at home and have a look again, maybe even image it if we have a clear evening

Sorry Rob, but the replies I'm getting from the pros on the other list I'm on are like this one:
I neglected to compare the 1-second image with the 5-second image. When you do so it is clear that both Mizar components are getting reflected, and both move together between the two images. Too bad it’s not real. L
Oh wel, maybe next time.

If we ever get out of the trade showers I can look again.
