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.
S E T- U P TRIPOD AND A C C E S S O RY T R AY
1. Stand Northstar Computerized Star Locator Assembly and attached tripod legs in
the upright position. Spread tripod legs to a comfortable distance.
2. Fold down the accessory tray braces and place the Quick Release Accessory
Tray on top of braces. (See Quick Assembly Diagram)
3. Turn accessory tray until it snaps into place.
4. Adjust tripod leg height to suit by opening tripod leg lever and extending tripod legs
to desired height. Clamp Tripod Leg lever closed when complete.
AT TACH TELESCOPE TUBE
1. Locate Main Telescope Tube.
2. Remove Telescope Tube Thumb Nuts from side of Telescope Tube.
(See Quick Assembly Diagram)
3. Position Main Telescope Tube Attachment Bolts through Telescope Tube Bracket at the top of the N o r t h s t a r
Computerized Star Locator A s s e m b l y. Make sure the telescope is pointing in the correct direction. (Logo on telescope
tube should be right side-up.)
4. Reattach Telescope Tube Thumb Nuts to Main Telescope Tube Attachment Bolts once Main
Telescope Tube and Northstar Computerized Star Locator Assembly are assembled together.
AT TACH FINAL TELESCOPE A C C E S S O R I E S
1. Locate Wide Field Finderscope.
For Refractor Te l e s c o p e s : Northstar Refractor Telescope Models have Finderscope Mount
already attached to Main Telescope Tube. Simply place the Wide Field Finderscope into the Finderscope Mount by
backing out the Finderscope Adjustment Screws to allow Finderscope to be fully inserted into the Finderscope Mount.
NOTE: Finderscope should be facing forward (Large end nearest the lens end of the telescope tube).
For Reflector Te l e s c o p e s : Remove Finderscope attachment nuts from Main Telescope Tube. Place Finderscope
Assembly over Finderscope Attachment Bolts and reattach Finderscope thumb nuts to Finderscope Mount Bolts.
N O T E : Finderscope should have large end of the finderscope facing open end of telescope tube.
2. Attach Low Power Eyepiece:
For Reflector Telescope Models: Insert lowest power eyepiece in the focusing mechanism
by backing out eyepiece set screw and inserting eyepiece fully.
For Refractor Telescope Models: Insert lowest power eyepiece into the penta mirror by
backing out eyepiece set screw, then insert penta mirror into the focusing tube of the Main Telescope Tube by backing
out focusing tube set screw.
3. Tighten all set screws to secure accessories.
4. Remove Objective Dust Cover and Finderscope Dust Cover Caps.
