4.Thread a lock knob (5) through each of the holes in the forks of the mount
4and tighten to a firm feel.
ATTACH THE VIEWFINDER
An eyepiece (1) has a narrow field of view. A viewfinder (2) has a wider field of view, which makes it easier to locate objects. The 5x24mm viewfinder has crosshairs to make it easier to line up more precisely with a target.
1. Note the two thumbscrews (25) threaded

place tube between forks
onto two bolts on the optical tube. Remove the thumbscrews from the tube.
2.Line up the two holes on the viewfinder bracket over the two bolts. Slide the bracket over the bolts. See Fig. 1, inset C.
3.Replace the thumbscrews onto the bolts and tighten to a firm feel.
ATTACH THE DIAGONAL MIRROR AND EYEPIECE
The diagonal mirror reflects the light from the optical tube to a more comfortable viewing position.

pole or a distant mountain or tower. Look through the eyepiece in the diagonal mirror and turn the focuser knob (23) until the image is sharply focused. Center the object precisely in the eyepiece’s field of view.
2.Look through the viewfinder. Turn one or more of the viewfinder’s alignment screws (3) until the crosshairs are precisely over the same object as you centered in the eyepiece.
3.Check this alignment at night on a celestial object, such as the Moon or a bright star, and use the viewfinder’s alignment screws to make any necessary refinements.
