Product Details

  • The AstroMaster 80AZS is a short refractor telescope perfect for terrestrial and celestial viewing. The short focal length is ideal for viewing star clusters and nebulae, while the erect image star diagonal makes the optical tube ideal for using as a spotting scope during the day.

    Setting up the telescope is a breeze and will have you observing in no time. Even on your first time out, you can assemble the telescope and its accessories in just a few minutes. The adjustable tripod legs allow you to customize the telescope’s height or place it on raised surfaces like a picnic table. An included accessory tray will help you keep track of eyepieces and other small items while observing.

    The total telescope kit weighs in at just 10 pounds—perfect for impromptu observing sessions or transporting wherever life’s adventures take you.

    Features of the Celestron AstroMaster 80AZ Telescope

    Manual Alt-Azimuth Telescope

    Navigate the sky with a panhandle Alt-Az control with clutch for smooth and accurate pointing. Move the clutch in an up/down, left/right fashion to track your object in the eyepiece.

    Accessories Included

    The AstroMaster 80AZS comes with two eyepieces (20 mm and 10 mm), erect image diagonal, and finderscope. The two eyepieces offer different magnifications to view your intended object. The erect image diagonal allows for right-side-up viewing ideal for terrestrial subjects but can also be used for celestial objects. The red dot finderscope will help you quickly center an object in your eyepiece for easier observing.
