Re: [APML] Gas hypered Velvia claim on Usefilm?



Jim,

Someone else already asked about the guiding. I was wondering about 
fitting
M31 on a 35mm negative with an 8" SCT. It is possible with a f/6.3 model
and a 6.3 reducer, but this introduces quite a bit of vignetting. I know
because I have an image with some field rotation from a poor polar 
alignment
that I had done to prove it.
