Just flip the power switch and this scope performs a self-diagnostic set-up and races off to the first alignment star. The large 80mm(3.1") diameter refractor lens captures more light. The two premium 1.25" Super Plossl eyepieces are premium 4-element oculars providing wider fields of view so you can see more of the sky at greater magnifications. The scope is equipped with Meade's new red dot viewfinder with LNT(TM), which makes locating objects quick and easy, and a Meade #494 AutoStar(R) controller (with an instructional DVD), which automatically locates and points the scope to over 1,400 celestial objects at the push of a button. The altazimuth mount and aluminum adjustable tripod complete this stellar scope.
