Here's a stupid question:

Why aren't there zoom functions on telescopes?

My binos have a you beaut zoom knob on them which makes them great for finding small things, like .... astronomical objects.

The other night I was pushing my 4.5 inch F8 (almost) reflector, with a 3x Barlow and a 4mm eyepiece, trying to get a better look at Saturn and it was damn near impossible to get the thing in view. It didn't help that my finder scope wasn't too well aligned for that magnification.

But I thought, if only I had a zoom so I could get it in frame and then close in.

Your wisdom please.
