Re: (meteorobs) Re Digimeteorography.

Stuart:
    I have never heard of anyone using a digital still camera for meteor
photography.  YK Chia from Singapores comments are sound.  You could use a
digital movie or hi8 video camera to record brighter members of the Leonids
provided the cameras are of low lux.  Some of the new digital video movie
cameras have "still image" capability for your other applications..  The
sensitivity of these cameras will decrease as you zoom out to wide angle but
increase in sensitivity as you zoom in to a narrow field of view.  You will
have to experiment to see which is the best setting for efficiency.  I use a
video Hi8 movie camera to record the screen of an Image Intensifier Tube.
This increases the faint magnitude capability recording meteors as faint as
you can see with your eye, sometimes fainter if you have a good intensifier.
Unfortunately new Image Intensifiers are expensive.
    For all-sky imaging, you could purchase a very low lux security camera
and fit it with a fast ultra wide angle lens.  I operate a Sandia Labs
all-sky camera that is used to record bolides (fireballs).  This system is
simply a security camera looking down at a silvered convex hemispherical
mirror.  This is capable of detecting meteors of -2 or -3 magnitude and
brighter.  Not efficient enough to record faint meteors but that is not the
purpose of this system.
