The magnification of the telescope depends on the focal length of the lens which is used. It can be calculated according to the following formula: lens focal length/ocular focal length(12.5)=magnification of the viewed image. So used with a 250/4 (smallest current lens with tripod bushing) your magnification would be 20X, I hope this helps Damian Vick Ko wrote: > > I'd like to see the rings of saturn.
