So its my second day using my telescope. I saw jupiter and i think its 4 moons. Although it was really small. So here is my question. I'm looking to but other eye pieces. But do all eye pieces fit any telescope. Also what is the lowest? I looked through a 10ml. My aperture is 150mm and my focal length is 750mm. I'm still learning. But the description when buying said I'll see jupiters cloud belt and the rings on saturn. What the best way to see these? Thanks guys!!:
