I have a Celestron Astromaster 90. Last night, I went to go see Jupiter, and with the 10mm eyepiece and the *angle lens?* (not sure if that's what it's called, but it's the thing that lets you look through the telescope from any direction other than straight through, mine is at a 90 degree angle) I got a decent image, although I don't have a Barlow, but I was able to discern the larger cloud bands and four moons, but the focuser was almost all the way out. When I took the thing* out, I was unable to focus on Jupiter at all. I could hardly see the moons and Jupiter was a massive white blob. I am an amateur and have no idea what's going on. If anyone knows what's going on and/or how to fix it, I would greatly appreciate it. Thanks!
