I'm hardly the expert but coincidently played with the Supra 800 for awhile
and
found, as I indicated in an earlier post, that it was great in short
exposure on
aurora but for anything over a minute I got intense green shift in the
colour
balance and I think Bert's more sophisticated assessment bears that out. It
was
also too grainy.

Don't forget the aurora though!
