- 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 )
