Finderscope assembly
Optical Finderscope
Red Dot Finderscope
Using the 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 adjustment knob, and altitude adjustment knob. 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.
Eyepiece assembly
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 it 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 finderscopes: 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.
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.
Remove two locking nuts from protruding bolts on the optical tube (close to the focuser).
Attach the finderscope bracket to these bolts on the optical tube and lock it in place with
thumbscrews.
Insert the finderscope bracket into a holder on the telescope tube and lock it in place with a
thumbscrew.
