    EQUIPMENT-
    Orion ST80 with Mogg 0.6 FR and a Mintron integrating camera. ST80 is
    piggybacked on a 12" LX200 which does the slewing and tracking. Focal
    Reducer is at max distance from detector and still capable of focus.
    FOV - 1.98 x 1.48 Degrees
    Time by IOTA-VTI GPS Time inserter (from VideoTimers)
    
    
    Equipment Notes - Luminance only is recorded to video.
    
    THIS IS A WIDEFIELD OBSERVATION.. 50mm Lens / PC164EX2 / Tripod

    COMMENTS:
    Observations from Friday night using the widefield setup.
    
    I had real problems reducing these two "simple" videos and almost threw them
    away. Lacrosse 5 was very low in the West. I always have a hard time with
    low elevation sats, like atmospheric refraction is not accounted for. Still
    no excuse for the timing scatter. Has to be that I picked bad stars in
    ObsReduce. Should I set a lower elevation limit? I think so..
    
    And speaking of ObsReduce.. I had a tough time getting the satellites to
    display where they were in relation to the stars, namely at the double point
    of USA 129, where there was this alignment.. A - B - Sat.. A was mag 7, B
    was mag 5, and USA 129 was 5.. Distance from A to B was equal to B to sat.
    0.08 degrees, and was a STRAIGHT LINE.. Both points, whether I used "use
    early/late" or not, showed it more like an 8 o'clock analog clock face..
    And this wasn't the only one.. Most of them were "off".. Hopefully it is
    because I used a few days old Classified file..
    
    That's a long way of saying feel free to discard any or all points.
    
    Also, by the time you read this, there will be a link to my website for the
    USA 129 Glint and Flare video. Even if the above points are "wrong" for
    position, the -0 Glint and -2 TIMES are accurate. The IOTA-VTI displays an
    error for any second that is wrong and tells you what second it was.
    (I am minorly involved with VideoTimers.com).
    
    If anyone wishes to fill out an FPAS report, my COSPAR and position are
    below.
    
    Now to see what I can screw up tonight (Saturday Night)..
    
    :-) 
    And in case anyone looks it up on GoogleEarth and A) thinks "that's a nice
    scope" and B) wants to try out the killer dog gauntlet, just remember C.. 
    "He's an American and they are ALL armed!"
    
    Ah.. The Joys of Quality Humor..
