Curiosity as to how a bright fireball might look inside the light blossum 
during an explosion is my downfall....

The system being retro-fitted now will utilize an 18" hemispherical mirror & 
1/3" CCD camera with an auto-iris, fixed 8.5 mm, 1:1.3 Computar lens 
designed for a 1/2 CCD. Initial Camera a 1/3" Sony SPT-M124 will be replaced 
with a PC164C. A Baader IR filter will be mounted (in) a machined adapter to 
fit inside the light shield of this lens up very close to the uv coated lens 
crown.

Preliminary indoor tests using Handyavi set for 640X480 RGB24 (30 FPS 
unfortunately), look workable with the camera about 40" above mirror peak. 
Fingers crossed.
