(meteorobs) Optimized filters for daytime fireballvideo capture?

[Chris Peterson]

Well, I get quite a lot of flare around the Sun, as well as internal 
reflections from the dome, so I know that an occulting disc would allow more 
of the sky to be seen in daytime. In addition, daytime meteor detection 
requires opening the iris as far as possible- just below the point where the 
sky saturates. That iris diameter would probably be large enough that the 
Sun could damage the camera sensor. When I was experimenting with detecting 
Venus and Iridium flares, I was careful to keep the camera in the shade (not 
a problem, since I was only interested in a small part of the sky for the 
tests).
