Exactly what i was wondering also, seems we have similar scopes. I have the astromaster 130eq 5.12" and 650mm focal length. i tried my 10mm ep with a 2x barlow lens which i believe should give me 130x mag, and i got a nice view of jupiter and it's moons, but it was still pretty small. I think the highest mag we can go to is 325x but apparently that will give us blurry images. Hopefully someone can help us out hey
