    Roger,
    
    I use a Night Owl Explorer NOCX3 night vision scope to observe sats and other things. It appears that the faintest stars I can see with it are the same magnitude that I can just make out with my 7 x 35 binoculars.  The magnification is a lot less than the binoculars of course, (3.1 X on the scope) but the vision through the scope far from good compared to a binocular view. 
    
    SPECS:
    GENERATION: 1
    MAGNIFICATION: 3.1X
    RANGE OF VIEW: 575'
    RESOLUTION: 24 LP/MM
    POWER: 3V LITHIUM BATTERY (NOT INCL)
    WEIGHT: 16OZ
    Dimensions: 7.2 X 2.3 X 3.2"
    FOV@1000yds: 628'
    FOCUSING RANGE: 5'+    
    
    For sat viewing I would not spend the money on this unit anyway.

    Has anybody had the opportunity to try out night vision goggles for
    satellite observing?
    
    I was watching a program on TV the other day, they had some shots looking
    through some NV goggles (trying not to type googles).   I recognized a very
    bright Pleiades system and realized the goggles might help out seeing faint
    objects.   I've never looked through a pair, but the view could be grainy
    (not sure if the grainyness is a video recorder byproduct or the goggle
    problem.)
