Re: [APML] Konica Centuria 200 Film



 Hey Keith...

     The spectral response curves for this film are much different than it's faster cousins. It looks strong in blue, but is completely blind in OIII and nearly blind in Ha wavelengths. Check it here:

      http://konicaminolta.com/products/consumer/photo/pdfe/pdf/csuper200.pdf

     Given this, combined with the still unknown reciprocity characteristics of any of these films, I'd have to say the 200 ISO would be a non-starter for deep-sky astro. (*maybe* usable for the Pleiades, but not much else) Spend your precious dark time with something better suited for the task... IMHO.

 Best...   :o)
