(meteorobs) Re: photos of perseids
As others have stated I would save your 3200 film for the Leonids this
fall. Use the Kodachrome 200 for the Perseids and save the fast film for
If the lens produces distorted images at the edge of the field tracking
will not help. You will have distorted dots instead of streaks. Stopping
the aperture down slightly may solve this problem.
Let us know your results!
