possible 'fogging' on the glass? I've noticed this when i take the binos out of the house and using them straight away (especially when I'm having a smoke while viewing).
I just use me shirt to 'demist' or sit them on the table for a little while and look again.
also another possible cause could be that Jupiter is so low in the sky in the evening, atmospheric aberration perhaps?
