Re: [APML] M35 (exposure times)

["Brian Larmay" <astrobri@ameritech.net>]

Hi Stuart!
I really dont or cant explain why Im getting so much....
I just open the shutter for as long as my skyfog limit will let me which is
about 12 mins @ f/4, and around the 7 min range at 1.8.
I never use the 1.8 anymore because of vignettting..

Still it is a mystery to me and I dont know why most of you go for such an
incredible amount of exposure...unless its how dark your skies are and your
stopping down further then me.

By all means if someone can give an explanation to why Im recording so much
in such a small amount of time, Im listenin:)

Brian
