    Hi Tom,
    Yes, I'm still here, but lurking more than observing, due to my new job.
    Glad to see you're enjoying the laptop observing method.  Actually, allot of
    people are doing it this way, I just made it a little more easier by making
    a mount to hold the laptop on my surveyor tripod.  Then I don't have to run
    back and forth from the laptop to the binos.  I merely look down at the red
    screen on the computer, then back up in the binos.  Really neat!  I am now
    working on a big parallelogram mount to hold a pair of Steiner 15x80 mil
    binos.  By the way, I just upgraded to Sky 6 and have some advise for you.
    Keep your Sky 5!  The Sky 6 looks a little nicer but falls short in the
    satellite department.  They have excluded allot of features that we have
    groan accustomed to in the Sky 5.  I have my Sky 5 and 6 loaded on the same
    notebook and very rarely go to Sky 6.
    An interesting story; We have an observatory a couple of miles away at a
    German College and one night I went out there and brought my equipment:
    20x-40x-100mm Myauchis, tripod, laser finder and computer running the Sky,
    set up to find satellites. I showed them EGP and some other flashers and
    pretty much got everybody out of the observatory and into the parking lot
    where my stuff was set up!  They all showed high interest in Sat observing.
    Maybe we'll have some new German members to See Sat!
    Take care Tom,
