Mark:
Meteors are more concentrated or closer together near the radiant. With
your 13 degree field of view this is probably a good choice. I generally do
that with my video spectrograph which covers around 25 degrees. Further
from the radiant the trails will be longer but more separated. I would
probably aim the camera toward the radiant at about 60 degrees in elevation
so you are looking at a thick portion of the atmosphere.
Your choice however. You can always use a monitor to see what you are
recording.
We are hoping for some clear breaks here. We have had a lot of rain
recently so I hope that ground fog doesn't roll in. The forecast for my
site on Vancouver Island is for scattered clouds. If this is the case I
will only set up my video system. If it's clear I also hope to use my film
spectrographs.
Good luck and clear skies:
