Companion to Polaris?

So now my question: When using Polaris to collimate at high magnification, have others been seeing this star, and has it caused any issues with getting a perfect collimation?

But Ab is a dwarf and likely not a visual object in any Earth based scope as it took Hubble to image it for the first time in 2006.
So what you have is a mystery, which is great fun.

I was at 245x when I noted a star next to Polaris.
Yes, Polaris is a well-known double. The companion is magnitude 9.1, 18.6" from the primary. It's an easy split at 100X in any decent telescope when the seeing is good. But the secondary is so much fainter than the primary that it's easy to overlook. It's far too faint to interfere with star-testing.
