Hello,
I bought a roll of Fuji Superia 800 and was
shooting with it at a festival today. I didn't use all 36 exposures and
was wondering if this film is any good for astrophotography. I've
forgotten what it actually said on the film cannister itself, but on the film
tube it came in it reads--Fuji Superia CZ135-36 800 ISO. Just wondering if
it's worth my time to finish the roll under the stars or not.
I have a Lumicon 2" Easy Guider and the (Lumicon)
recommended 3X Prism Diagonal. I guide with a 10mm illuminated
reticle. I'm using a 480mm f/6 80mm achromat. My problem is
not so much in finding a guidestar (although that is a challenge at times),
but having one bright enough that I can actually see well enough to guide with,
without having to use averted vision. Is there a reason for using a
prism instead of a star diagonal? I realize having a 3X magnification is
going to make the guiding easier and more accurate, but would I get brighter
guide stars by using a star diagonal and 2X barlow? Would I be able to
focus the guidestar with this set-up? The sky here is socked in or I
would try it out. I'd appreciate any thoughts or knowledge anyone might
bestow upon me.
