paul mc c Posted January 20, 2015 Share Posted January 20, 2015 Hi and welcome Jason,with your scope you would be better using the 12.5 or the 20mm as the others may be to much magnification. Link to comment Share on other sites More sharing options...
ronin Posted January 20, 2015 Share Posted January 20, 2015 I generally advise an eyepiece about the same as the f number of the scope.Yours is 9.2 so I would say a 9mm or 10mm or something close.A 10mm would deliver 70x which should be reasonable on Jupiter.You will not see the GRS but a couple of bands easily and perhaps outer 2 bands may just show up, somewhat vaguely.I personally would stop at a 7mm for 100x, if you go down that route.Most scopes do not deliver the magnifications claimed.The eyepieces supplied are simple Huygens and Ramsden eyepieces both have inherent problems in the basic design.The 2.5mm and the 4mm are really little or no use.I also suggest not using the erecting eyepiece.
