RE: (meteorobs) photos of perseids
Hi,
thanks for all the responses so far! I think I have to
answer a few questions at this point.
My primary goal is to get aesthetically pleasing
images. Hard with the Moon shining, but the goal ist to have some pretty
pictures of meteors.
Bob is thinking along the right lines, longer exposures
are better. I'm doing this with so many cameras because I want to increase the
likelihood of catching a meteor, not because I have film to burn. I'm a
high-school student with a love for astrophotography and especially meteors,
which is why I'd like to capture them on film. In fact, I have only 5 rolls of
T-Max 3200 and 5 rolls of Kodachrome 200 (also said to be OK for meteors), so
that's enough for two nights if I expose between 5 and 10
minutes.
However, getting to what Bob said - equatorial tracking
would be better - if I do track the cameras, I will be able to see the distorted
stars in the edges, which doesn't look very nice (I did that
before).
Maybe a "compromise" brought about in part due to the
moon would be mounting the cameras on the equatorial drive, stopping down to
f/2.8, still using ISO 3200 film and exposing for 5-10 minutes, far away from
the Moon? Stopping down reduces vignetting and distortion, but reduces the
amount of meteors captured, however allows me to expose longer. Besides, I've
only used 200 and 400 speed films in the past, so 3200 should capture many more
meteors than I'm used to, even if the lens is sopped down one and a half stops.
What do you think?
