Thank you for purchasing the Bushnell 78-3612 Reflector Telescope! Your new telescope has been
designed and crafted with the highest standards so that you may have years of enjoyment and use out of
this wonderful window to the heavens. This product comes complete with everything you'll need to
explore your universe including a precision rack and pinion focusing mechanism, premium adjustable
aluminum tripod, superior all-metal main telescope tube, and wide-field 5x24 finderscope. Whether
you are just starting out in astronomy or you are an avid astronomer we wish you all the best with
your telescope.
Please utilize this manual to its fullest potential by reading it completely before you attempt to
assemble and use your new telescope. Once assembled, we've included a basic guide on how to get started
in astronomy at the end of this manual. While this is not a complete guide, it will give you some initial
pointers. As you advance in ability, we would highly recommend a supplemental star atlas, beginning
astronomy guide, moon map, or any other guide as you travel on your journey through the universe.
