    Default Eye piece for Celestron 130EQ



    Yesterday I have finally seen Saturn and the rings with the telescope, 650mm focal length and with the 10mm Eyepiece. It was small, but I saw the rings and I think I also saw Titan next to it... tiny and faint, but it was were sollarium said Titan is. Now my main objective was to see Saturn. Now I can relax and enjoy the sky

    I'm thinking of buying a lower eyepiece, the 3,2mm will give me 203X, 4mm 162,5X. I've been reading that 200X for the 5 inch telescope is pushing it... so I'm ruling out the 2.5mm one that would give me the maximum theoretical magnification of 260X that the specs say this telescope is capable of.

    So, should I go for the 3.2mm or 4mm one?

    And another question is, 1X vs 2X, that means that the size of a sphere is twice as big but it is referring to the length of circumference? I mean it really isn't the diameter of the sphere as for example Jupiter is 11.2 times the diameter of the earth and 1321 the volume of earth...

    I just realized it's the wrong forum... so maybe if this gets mooved to the eyepiece one, I'll get some suggestions.
