With its moderate f/6.7 focal length and 90mm aperture, this mid-size refractor telescope is a great choice for serious beginners.

The wide-field optics of the BX90 EQ Refractor makes it easier to find objects in the night sky compared to longer telescopes. The refractor’s substantial 90mm (3.54″) objective lens collects much more light than typical starter scopes for brighter, more pleasing performance on a wide variety of interesting celestial objects. Whether you’re going after powerful views of craters on the Moon, or looking for wide views of star clusters beyond the Solar System, the versatile Orion BX90 EQ Refractor fits the bill. Internal, knife-edge baffles help minimize off-axis reflections to optimizes contrast for sharp and crisp observations.

The included EQ-1C equatorial mount comes with useful slow-motion controls which can be used to manually track objects as they appear to move across the sky. You can even add an optional EQ-1CM motor drive (sold separately) for hands-free tracking. The EQ-1C mount sits on top of a sturdy tripod with a clip-in accessory tray that enhances stability and provides a spot to stow idle eyepieces and accessories. The tripod features extendable legs which can be adjusted in height for comfortable use. Once assembled, the entire BX90 EQ weighs 15.5 lbs. for easy portability.

This complete telescope setup comes with everything you need to star stargazing right away. Two 1.25″ eyepieces provide different magnification options right out of the box. Use the included 25mm Kellner for wide views at 24x magnification, and boost magnifying power up to 60x with the 10mm Plössl eyepiece when you want to take a closer look. The Orion BX90 EQ Refractor Telescope also includes a 90° star diagonal for comfortable nighttime viewing and a red-dot sight to help aim the telescope.
