I have read that its possible to see the furtherest out moons from a dark steady sky using a knitting needle end as a mask ( block ) on Jupiter its self , but it would be very hard .

You need a blackened tube 30mm in diameter about 100mm long with the needle poking thru one side to 1/2 way about 25mm from the eye end and mounted on an EQ mount with a solid support to keep your head very , very still . .
I think I will just use my scope .

Dennis DeCico of S&T mag did it once years ago , he has telescope eyes they say .
Brian.

Yes Brian, but it's much easier to see (naked eye!) the Jovian Gallilean satellites with the aid of a small brass or glass 90-degree angle 'visual' back..!
