Celestron StarPointer Finderscope
The Celestron Star Pointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece.
A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the StarPointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view.
If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you’ll get the best use out of each of your finders.
How to Align the StarPointer Finderscope?
The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece.
Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.

- Q: Why can’t I see the red dot when I turn on the finderscope?
- Q: My finderscope will not turn on. What could be wrong?
Ans: Assuming your battery arrived with full power and with the plastic connection strip still in place, follow these steps:
- Remove the plastic connection strip and try again to turn on your finderscope. Make sure to rotate the “ON” knob at least 30° and give the red dot 1 second to appear.
- If step 1 did not work, remove the battery door (FIG (A)) and check the bent metal tab that contacts the (+) side of the battery (FIG (B)). Verify that it is making solid, continuous contact. With the battery door removed, Apply pressure to the metal tab with your thumb and turn on the finderscope, by rotating the “ON” knob clockwise, as shown in FIG (C). Can you see the red dot now? If not, go to step 3.
If so, the metal tab is the issue.
To fix this, remove the battery, bend the metal tab inward towards the cavity left by the removal of the battery. and press the arm of the metal tab down into the plastic housing on the areas pointed to FIG (D). Replace the battery and battery door and turn on the finderscope.
- You may have a depleted battery. Remove the battery door and battery. Replace it with a fresh one. The battery is a 3V battery, model #CR2032. After replacing the battery, repeat step 2, just to be sure, then test the finderscope. If it still does not function, the unit is defective. Contact Tech Support for a replacement.
Note: Be sure to turn off the StarPointer finderscope when not in use to conserve battery power. New batteries can be purchased online or at watch/electronic stores.
