Re: (meteorobs) Ulrich's software
Hi Tom,
I'm glad you like the software. Actually, it was originally a BASIC program
that was featured in Sky & Telescope. I just rewrote it into a Windows
program. It is in fact designed to calculate the efficiency of a setup in
capturing as many meteors as possible, *but* this also means more bright
meteors. If you have a setup that captures *only* the bright meteors (like
35mm film and a fisheye lens), then you'll be capturing very few meteors,
and those will all *look* faint on the film. If, instead, you're capturing
meteors down to 2nd magnitude, the bright ones you do capture will really
look bright! As you go fainter, there's more meteors, and if you're
capturing a 2m meteor as well with one setup as a -1m meteor with another,
then the first setup is actually much better at capturing the brighter
meteors! Tell me if this isn't what you were thinking of....

Subject: (meteorobs) Ulrich's software
Ulrich,
I was just playing with your software and enjoyed it very much. It appears
the focal ratio plays a bigger role than the focal length of the lens. I am
guessing the criteria would be to capture as many paths as possible
regardless of magnitude.
>From a purely esthetic point of vew, I would be interested in capturing as
many bright meteors as possible (say from 0 mag and brighter.) This would
perhaps put more emphasis on the focal length rather than the focal ratio.
Could you introduce this change in criteria into a second version of your
program?
Thanks again for sharing your software,
Tom
