(meteorobs) Tips for Meteor Photography (Perseids)
Hi,
I'm going to try capturing some Perseids on film with a 4-camera array (a
cluster of T70s). I'll be using Kodak T-Max 3200, but it's the first time
I'll be using the film and I don't want to make any mistakes. Therefore, I'd
be interested if someone that has used this film could tell me an
approximate exposure time for medium-bright skies (4-5m limiting magnitude)
and dark skies (6m). I'm shooting at f/1.7 with 50mm lenses.
That brings up another question. At f/1.7, the lenses have quite a bit of
vignetting and very distorted stars in the corners. Stopping the lenses down
just lets me lose meteors, so I'll stay at f/1.7, but should I track the
cameras on an equatorial mount or let the stars trail through the field?
This won't have any effect on the vignetting, but the distortion won't be
visible if the stars trail. However, it will be more difficult to find a
meteor in a star trail field and even if it goes at a 90-degree angle to the
star trails, it doesn't "pop out" as well. What would you all recommend?
I'm also going to use my home-built allsky camera with 9x12 sheet film and a
30mm f/3.5 fisheye lens with T-Max 400 film, I think I can expose for 1 hour
with that, but I'm going to test it in advance.
Clear skies,
