Product Description
Once the base is installed on your scope, the black plastic finder itself slips onto the base and is clamped in place by two screws. Azimuth and altitude adjustment knobs allow you to line up the Star Pointer with your main scope optics. The dovetail is not a quick release type, so the foam of your scope's carrying case may have to be cut to fit the finder outline for easy storage.
An on/off switch on the finder body, plus a brightness control, allow you to match the finder brightness to all lighting conditions, day or night. The finder uses one user-replaceable 3 volt BR2032 or CR2032 lithium camera battery (supplied, but not guaranteed by Celestron to be fully charged when received). Battery charge and battery life are not covered by the finder warranty. When it is time to replace the battery (readily available at Walmart, Radio Shack, camera stores, etc.), you can use either of the above batteries or a BR2025 or CR2025.

Reviews
For urban or beginner use the slightly extended size (not pinpoint, not bloated, maybe 1-2 arcminute?) of the well defined dot is easy to see and aim with.
With reasonable performance and very light weight this is a handy and low-cost add-on to small-medium scopes.
Viewpoint is closer to tube than with bigger RDF's so mounting on dew shield at front, or back of OTA near focuser attachment, gives you more 'face room' in use. Also, the window you view through is a little smaller than more expensive RDFs, so only 4 stars, but still a very good and useable value. (Posted on 8/4/2017)
