NOTES:
----------
(1) Had to do major servicing on homemade mount- first time in about a
     decade - one gear badly worn- missing full profile teeth in one 
location so
    was   missing a "step or two". Then whilst repairing this found another
     gear was slipping sometimes on the gearbox shaft. This all explains
     why I appeared to have had so much backlash in elevation.

(2) Consequently observed in very high cirrus conditions - no problem
     because of the large aperture used but tended to mess up the
     magnitudes determined.

(3) New object for amateur catalog -- ISON OBJECT SO62200 80578 09756A
     found by accident crossing field of view - appeared reasonably steady
     and since elements about 3 weeks old maybe not too subject to solar
     radiation pressure - low perigee.

(4) Plan to change to wide angle setup with bright of moon and approaching
     launch of next X37B.

(5) Some magnitudes really look weird - extreme cases deleted. But magnitude
      +5 for #33490 is a first ever - usually about 3 magnitudes fainter 
- did not
      look +5 !  Nothing changed in setup except seeing was good ~ 8 arc 
secs
      and collimation of scope reasonably good but that should not 
affect the
     magnitude that much.

Cheers
Greg
