Notes (S00082)

- 5.1/4 hour imaging session in which the main aim was to record 35mm film images of comet C/2004 Q2 (Machholz) and other objects using SLR camera mounted on top of the LX200 scope.  [ Copies of Film Images will be be posted when available ]
- Opportunity was also taken to record CCD images of same objects using ST7 CCD camera,  and LX200 with a focal reducer bringing 8" f/10 scope down to f/7. 
- More notes (including investigating into problems with tracking in NW sky / use of counter weight balances )
