I have a 1000mmm lens which is sharp and would be the equivalent of a 1600mm on my dslr but I think Saturn would still just be a speck.
I would try anyway but it is overcast here.
A month or so ago the local astronomy club had a demo and I peered at Saturn through a couple of gi-normous scopes — and Saturn was recognizable, but tiny. Had the same experience years ago, same club, different location, through a Celestron C-11 (or maybe it was even bigger than that).
