Sorry for bad English.

A daytime bolid it's a very rare event, perharps from a place it can 
to be saw one time each 10 years or more then I think that nobody 
should see at it specifically, but if a people want to do this I think 
that a common camera can took easy a similar event without special 
accessories, the only accessory that, perharps, can aid it can to be a 
polarizer filter for to clear the sky. Naturally the camera must never 
see the Sun.
Best greetings.
