Hi Guys I just recently picked up a celestron 130 off a fellow member off this site and it came with 3 lenses a 10mm, 20mm erecting and a 4mm plossl, Now I see jupiter and its moons nice and clear with the 10 & 20mm but they are small. What is the 4mm plossl best for? and what other eyepieces could you recommend that would give me nice crisp images with more detail if that is possible at all or are the ones that I have good enough Cheers. P.S Jupiter is not good at all through the 4mm. Please explain the what the different sizes are best for, eg 4mm moon - 20mm distant planets etc Thanks
