Product information

The PowerSeeker 50 is a refractor telescope perfect for terrestrial and celestial viewing on the go. The PowerSeeker can view the planets, moon, star clusters and brighter deep sky objects like the Orion Nebula and Andromeda Galaxy at night. 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, so you can begin 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 telescopes height or place it on raised surfaces like a picnic table. 

Manual Alt-Azimuth telescope

Navigate the sky by moving the telescope up/down, left/right fashion to track your object in the eyepiece.

Accessories Included

The PowerSeeker 50 comes with four eyepieces (20mm, 12mm, 4mm, and 1.5x image erecting eyepiece), star diagonal, finderscope, and a 3x Barlow lens. The four eyepieces offer different magnifications to view your intended object. The 3x Barlow lens triples the magnifying power of each eyepiece. The star diagonal allows for right-side-up viewing ideal for terrestrial subjects but can also be used for celestial objects. The finderscope will help you quickly center an object in your eyepiece for easier observing.
