If you stick a magnifying glass in front, it will focus it to a point. They Aries series is not made stock with anything you can rotate to change focus though, they are naturally focused at infinity. With some optics and a little inventiveness you could modify up your own upcollimation/focus unit though.
I'm still working on adjustable focus/collimation for my Aries (see the experiments and modifications thread) Parts take a while to come in sometimes...
