Quick Set-up Guide


Your AstroMaster 70AZ/90AZ includes: optical tube w/ built-on StarPointer finderscope, pre-assembled tripod with center leg brace and altazimuth mount attached; two eyepieces; erect image diagonal, accessory tray, lens cloth, battery, owner’s manual, and The Sky™ CD Software.

To set up the tripod, spread the legs outward until they are fully extended. Extend each of the three tripod legs down 6-12".

Use the three tightening screws located at the bottom of each leg to secure the extended legs in place.

All three legs should be the same length to provide a level platform for the telescope.


To attach the accessory tray, line up notches and turn clockwise until tray tabs lock into place with the tripod brackets.


Properly assembled, the accessory tray should appear as pictured above.

Here is how the fully assembled tripod and mount should appear.

Next slide telescope tube into the mount. Be sure to back out fastening screws to allow enough clearance for the dovetail.

Center dovetail in the mount and tighten fastening screw. For added security tighten the angled lock down screw next to the fastening screw.
