Bullet Notes from CCD Session
 
Bullet NGC 2126 (Open Cluster)
Bullet NGC 1931 (Open Cluster)
Bullet IC 405 (Flaming Star Nebula)

Notes (S00075)

- Imaging session was with a focal reducer bringing 8" f/10 LX200 to f/7. 
- Images were recorded with ST7 CCD camera. Filter Wheel with CBVRI filters
- 2.5 hour session (1.5 hour imaging) - very cold 
- initial slew to NE sky caused cables to drag, forcing the CCD camera to rotate clockwise by 9 deg. (lost about 30 minutes )
- session ended when snow began to fall
