Your tri-ocular eyepiece holder can be used to instantly change the power of your telescope by simply rotating the
holder from one eyepiece to the next. To change the power of your telescope:
1. Grab the rotation ring securely with one hand. See figure 2.
2. With your other hand, rotate the tri-ocular holder (eyepieces) until the desired
eyepiece is facing upward. You will feel the eyepiece click into place.
Your tri-ocular holder can also be used to change the viewing position of each eyepiece.
To change the viewing angle:
1. Grab the rotation ring of the tri-ocular holder.
2. Rotate the rotation ring (with eyepieces) to the left or to the right
approximately 45° until the eyepiece clicks into place.

The 5x20 finderscope comes installed in a bracket that pivots for convenient use.
1. The finder bracket has a small tab on its base that slides into the opening
located on the left side of the telescope tube (between the silver telescope tube and the black rear cell).
2. Once installed, you can pivot the bracket into the desired position and secure it using the locking screw.
1. Locate a distant daytime object and center it in a low power eyepiece in the main telescope.
2. Look through the finderscope and take notice of the position of the same object.
3. Without moving the main telescope, turn the adjustment thumb screws located around the finderscope
bracket until the crosshairs of the finder are centered on the alignment object.
1. Loosen the pan handle (8) by twisting it counterclockwise one full turn.
2. Loosen the Azimuth locking screw (13) (PowerSeeker
3. Look through the finderscope and pan the telescope until the object appears in the field of view. Once it's in
the field, tighten the pan handle and azimuth lock.
1. Once you have found an object in the telescope, turn the focusing knob (7) until the image is sharp.
2. To focus on an object that is nearer than your current target, turn the focusing knob toward the eyepiece (i.e.,
so that the focusing tube moves away from the front of the telescope). For more distant objects, turn the
focusing knob in the opposite direction.
3. To achieve a truly sharp focus, never look through glass windows or across objects that produce heat waves,
such as asphalt parking lots.
1. The PowerSeeker uses an erect image Tri-Ocular holder to give you correct images when viewing land or
celestial objects. However, the finderscope will always give inverted (up-side-down and backwards) images.
