    I will sk him again,
    
    He told me that is was moving,  0.02 deg a minute. That works out to 1.2 
    min per min true?
    
    And using relatively high magnification to view Saturn, With the planet, 
    and it's other moons in the field, I guess he could see this motion.
    
    But I will get a verification on the rate.

    > Could you verify the angular rate? I think you said that the speed was about a minute of arc per minute of time. If so, that's really close to the limit at which motion is perceived as motion. It's not impossible, of course. And even that slow motion is detectable by comparisons over time. I just wonder whether this was consistent with your observer's actual observations. The Moon's motion relative to background stars is half a minute of arc per minute, so if the quoted speed is correct, that's very slow. There are a number of satellites on elliptical orbits with very high apogees. When at apogee, they move much more slowly than geosynchronous satellites. That's just a general suggestion --I don't have any candidate objects.
