Hi Peoples,

: I have a little 5" scope and I am just wondering if a 10" scope doubles the size of what I am looking at or is it the EP's that do all the work.
Also, I was having a look at Jupiter this morning

and I seemed to have trouble focusing it properly using the Barlow 2x or the 6mm Planetary EP. Even when we have a look at Saturn we seem to have the same problem. We get nice clear views with the 10mm and am just wondering what the problem may be

. It doesn't help everytime we try to focus the whole lot shakes.
