Comment Don't use a mount! (Score 1) 85
When we photograph meteors for genuine data collection, we don't use a mount at all. We set up a ring of cameras with each covering several degrees of sky, and let them all take five or ten minute exposures. It's your best hope of catching a bright one and several faint ones. If you're using a decently short lens (50mm, 35mm), (a) you'll catch more meteors and (b) the star trails are less notable, or you won't care about them.
Remember, with meteors being an atmospheric phenomenon, you'll catch more closer to the horizon than looking up. (You're looking through more air.)
And it makes no difference if you're looking toward or away from the radiant for meteor count.
