WHERE DO I START? Your Bushnell telescope can bring the wonders of the universe to your eye. While this manual is intended to assist you in the set-up and basic use of this instrument, it does not cover everything you might like to know about astronomy. Although Northstar will give a respectable tour of the night sky, it is recommended you get a very simple star chart and a flashlight with a red bulb or red cellophane over the end. For objects other than stars and constellations, a basic guide

DETAILED ASSEMBLY 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, eyepieces, and various accessory lenses.

DETAILED ASSEMBLY (CONTINUED) M FOCUSING TELESCOPE 1. After selecting the desired eyepiece, aim main telescope tube at a land-based target at least 200 yards away (e.g. a telephone pole or building). 2. Fully extend Focusing Tube by turning Rack and Pinion Focusing Mechanism. 3. While looking through selected eyepiece (in this case the 20 mm), slowly retract Focusing Tube by turning Rack and Pinion Focusing Mechanism until object comes into focus.

M ENJOYING YOUR NEW TELESCOPE 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 good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take. 2. The first thing you need to do after assembling the telescope

M HELPFUL HINTS 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 possible view from a location that has relatively few lights. This will allow you to see much fainter objects. You’d be surprised how much more you’ll

Repeat this process for STAR 2 and press ENTER. After this step is completed, you will see a display that reads: (Note: The more stars that appear on the second line of the display the better, up to 5) After the two star alignment is complete, your Northstar now knows with pinpoint accuracy where
