Orion StarMax 90mm TableTop Maksutov-Cassegrain Telescope

An included Orion EZ Finder II reflex sight lets you aim the 90mm telescope with ease.

Following a simple alignment procedure that parents can help with, you can use the EZ Finder II sight to accurately aim the StarMax 90mm TableTop Mak-Cass telescope at objects in the sky like the Moon and bright planets. Once aligned with the telescope, just turn on the EZ Finder II and peer through the sight's small circular viewing window so you see the red dot, and move the telescope until the red dot is on the object you want to see to place it in the telescope's field of view.

Start stargazing with the 25mm eyepiece for 50-power views.

The included 25mm eyepiece provides a 50-power view in the StarMax 90mm Mak-Cass. The 25mm is a great eyepiece to use first when you stargaze with the telescope each night, since it provides a larger, less magnified window of night sky for you to view. This lower magnification makes it easy to find objects to explore in the night sky.

Increase magnifying power with the 10mm eyepiece.

After you've scanned the skies with the 25mm eyepiece in the StarMax 90mm telescope, take a closer look at interesting objects by swapping out the 25mm with 10mm eyepiece to boost magnification from 50x all the way up to 125x. The more powerful view in the 10mm focal length eyepiece reveals details such as craters and mountains on the Moon, the rings of Saturn, and brighter moons of Jupiter.

Use the included 90ø star diagonal for comfortable views of the night sky.

A diagonal "bends" the light path of a telescope so you can enjoy the view without having to contort yourself into awkward positions to peer into the eyepiece. The 90ø star diagonal that comes with the StarMax 90mm TableTop Telescope yields bright images and provides a comfortable right-angle viewing orientation for nighttime stargazing of the skies above.
