DETAILED ASSEMBL Y No tools are required for assembly of your telescope. Remove all components from the carton and identify all components. It is a good idea to lay all the parts out in front of you before assembly. Since your telescope is a precision optical system the parts require careful handling—particularly the onboard computer, telescope, [...]

M ALIGNING FINDERSCOPE Look through Main Telescope Tube and establish a well-defined target. (see Focusing Telescope section) Remove plastic insulator from between Red Dot Finderscope battery and battery clip. Turn Red Dot Finderscope on. Looking through Red Dot Finderscope, turn adjustment wheels until the red dot is precisely centered on the same[...]

M ENJOYING YOUR NEW TELESCOPE 8. 1. First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When you have developed proficiency at this level, other objects become g[...]

M HELPFUL HINTS 9. 1 . Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you’ve drawn a crowd with your new telescope. 2. If possib[...]
