Optical finderscope

Optical finderscopes are very useful accessories. When they are correctly aligned with the 
telescope, objects can be quickly located and brought to the center of the view. Alignment is 
best done outdoors in day light when it's easier to locate objects. If it is necessary to refocus 
your finderscope, sight on an object that is at least 500 yards away. 

For 5x24 and 6x24 finderscopes: turn the scope end to adjust the focus. For 6x30 finderscope 
loosen the locking ring by unscrewing it back toward the bracket. The front lens holder can now 
be turned in and out to focus. When focus is reached, lock it in position with the locking ring.

To align the finderscope, choose a distant object that is at least 500 yards away and point the 
telescope at the object. Adjust the telescope so that the object is in the center of the view in 
your eyepiece. Check the finderscope to see if the object is also centered on the crosshairs. 

For 5x24 and 6x24 finderscopes: use three adjustment screws to center the finderscope 
crosshairs on the object. For 6x30 finderscopes: adjust two windage screws only.

Red dot finder

The red dot finder is a zero magnification pointing tool that uses a coated glass window to 
superimpose the image of a small red dot onto the night sky. The red dot finder is equipped with 
a variable brightness control, azimuth and altitude adjustment screws. The finder is powered by 
a 3-volt lithium battery located underneath at the front. To use the red dot finder, simply look 
through the sight tube and move your telescope until the red dot overlaps the object. Make sure 
to keep both eyes open when sighting.
