The Celestron Astromaster 80AZ 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.
