Odd viewing

[Piers127]

Okay, stupid question time.

At the weekend I was watching the Pleiades and there was a reddish extra star about the size/colour of Betelgeuse just above and to the left of the point where the bottle-shape widens. It's not there any more. It did seem to be stationary as I watched it for some time.

Any ideas?

Sounds strange, could it have been something on the mirror/lense?

I thought of that, no. The object was stationary and only visible when looking there. It was weird.
