: Hi, I recently got a Celestron G-3 and got my first : view of Jupiter on 1/19 at about 8:30PM Pacific Time. : I only saw three moons, does anyone know how to find : out which moons are occluded by Jupiter? My guess : is that it was Io, but it's just that, a guess. Also, : what do you think would be the best set-up for : planetary viewing? From what I've read here, probably : a 2X Barlow with a longer eyepiece, but who makes a : high quality Barlow? : Thanks : P.S. My name's Jacob, but no matter what I do this thing : says I'm "Morgan"???

i Jacob, because of the tilt of the 4 moons' orbits as seen from Earth, all 4 of them will travel behind the disk of Jupiter. As far as high quality barlows, I hear the Celestron Ultima is one of the most highly regarded. Also, if your main interest is planetary viewing, a good orthoscopic eyepiece is hard to eat. University Optics has a line which are well spoken of as well as economical.

Best regards, Bill B.
