Bushnell 78-7880 80MM REFRACTOR Detailed Assembly, SET-UP Tripod and Accessory Tray

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.

SET-UP TRIPOD AND ACCESSORY TRAY

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.

ATTACH 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 Assembly. 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.

ATTACH FINAL TELESCOPE ACCESSORIES

1. Locate Wide Field Finderscope.

For Refractor Telescopes: 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 Telescopes: Remove Finderscope attachment nuts from Main Telescope Tube. Place Finderscope Assembly over Finderscope Attachment Bolts and reattach Finderscope thumb nuts to Finderscope Mount Bolts.

NOTE: 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.
