When we were in the Keys 2 years ago, 350x was ideal on Jupiter with my 10"
Mak-Cass,

35x per inch in great seeing? Interesting. I always leave out the seeing
aspect. Seeing here is often such that using over 200x in any scope results in
poor images. So while I am happy to contribute my two cents, I must alos at
this point make it clear that I make no claim to have figured it all out...yet.

but seeing detail on Gannymede was impossible until we reached
powers
of 600x to 900x. At 900x, subtle detail stood out during moments of excellent
seeing on Gannymede, but most surface detail on Jupiter itself was much less
pleasing.

I would love to see detail on Ganymede this season.


There is no one power that works for every object. That's why Uncle Al makes
a
gazillion eyepieces, and you all ought to buy one of each (two if y'all have
a
binoviewer - er, a Baader bino if'n ya want t' see the sharpest detail).

Preaching to the choir uncle Rolando. I shudder to think how many eyepieces I'm
up to now.
