Re: [APML] "challenge"
A double exposure would be the way to go, *if* the scope/camera/autoguider
setup could be left _untouched_ for a day or two. One could take a long
exposure of the Crab Nebula before Saturn gets in the FOV. Then just image
Saturn with a quick exposure on the same frame during it's M1 transit.
Anybody with a permanent setup in an observatory would have a decent chance
at this. Of course focus could be off a bit between days, and there could be
some film creep. But nobody ever said this hobby is easy <g>.
