Re: (meteorobs) Video Quadrantids
Hi ykchia,
The integration level is 4x (the effective base of departure is 50frame/sec)
therefore one exposure of 0.08 sec.
The video lens is one Computar aspherical high speed for 1/2 inch format.
Other focals exist: 12mm F/0.8, 6mm F/0.8, 3.8mm F/0.8 and 2.6mm F/1.0. The
lens are truly much good ones.
On the television (not in video tape) the effective magnitudine limit is 6.3
in blue stars and 6.9 in red stars approximately.
Best regards,
Roberto Haver

Hi Robert:
Very impressive LM - with such a large FOV.. What
integration level are you using x2 or x4?
Is this with a video lens?
