What was this?

I just came in from observing Jupiter and the moon (at about 11:00pm).

At steady times I had some nice views (6" refractor) and bino.

While panning around I passed over a bright cigar shaped area in the shape of a reverse "c". It was just north of Jupitar and towards the west. It was about 3 times the size of the moon from north to south and 1/2 a moon in width. I observed with the bino and mono at several powers and it was always there. I could not see it with the naked eye in my LP skies.

Is this an artefact or a messier object?

thanks howard

Sounds like an internal reflection of the moon off of something in your optical train to me... Just a thought.
