    Notes:
    ------
    (1) A good too warm (~ 22 deg C) night abruptly terminated by clouds.
    
    (2) USA 186 #28888 not seen on first pass- may have been too low/faint.
        No second pass due to clouds.
    
    (3) Several satellites not seen so will have to make an effort to find
        them - #90025 and #90058.
    
    (4) Unknown #91092 seen whilst tracking Noss 0 (D). Difficult to estimate
        magnitude, probably in range 7.0 to 7.5. Cant find a match in my
        satellite databse. Appeared steady. Ends of the trail produced in the
        exposure not too well defined so there may be a little scatter in the
        RA/Dec reported. Time is okay.
    
    Update on Bartels SCOPE program:
    -----------------------------------------------
    
    I "Modified" my 6 inch f/5 celestron on a Super Polaris equatorial mount
    to work with CoSaTrak as an altazimuth. However due to mechanical problems
    with the telescope possibly colliding with the pier/mount/motors in the
    dark I decided to try the telescope as an equatorial. CoSaTrak cannot
    drive an equatorial so I opted to use Mel Bartels SCOPE as I thought this
    could do the job and I restored the polaris mounting back to an equatorial
    and fitted stepping motors on the polar and declination axis. SCOPE
    drives the telescope fine and I had high hopes but then discovered that
    although RA/Dec and alt/az are displayed on the program SCOPE monitor
    screen, the alt/az shown is NOT the conventional alt/az so is totally
    useless.
    
    I must confess I do not understand why it was chosen to do it this way
    as its a classical example of conversion of of co-ordinates from
    celestial to terrestial and vice versa. All the required information
    is available in SCOPE so its a mystery to me why the displayed RA/Dec
    could not be converted to show true azimuth/elevation instead of showing
    information which is of no use to anyone. This problem then effectively
    means that one must work in RA/Dec only-obviously SCOPE was only
    planned for astronomical viewing. I have still to try the program under
    the "stars" but having to work in RA/Dec is a "pain" and has dampened
    my enthuisiasm for the program.
    
    
    I will keep readers informed of progress or lack thereof.
    
    Cheers
    Greg
