Product Details

  • This refractor telescope goes the extra distance in introducing the novice to the wonders of the night sky. Compared to a 60mm refractor, the Observer II 70 EQ can reveal an even greater variety of stellar gems and provide greater resolution of old favorites like the Moon, Jupiter, Saturn, and the Orion Nebula. The Orion Observer II 70 EQ Refractor Telescope features an achromatic glass objective lens that's 70mm in diameter, with a focal length of 700mm (f/10). This lens takes in 36% more light than a 60mm lens for brighter, clearer views. Bottom line: you'll see more than you would through telescope with a smaller aperture.

    The telescope tube is supported by the included Orion EQ-1B equatorial mount. Also made of aluminum, the EQ-1B mount is designed to mimic the rotational axes of the Earth, which in turn allows you to manually "track" celestial objects with the Observer 70 refractor using slow-motion controls.

    Along with the refractor telescope, the accessories included in this value-packed kit have been selected to enhance your stargazing experiences.

    • A 90° star diagonal is included for comfortable nighttime viewing.
      A diagonal bends the light path of a telescope so you can view the sky comfortably. Without a diagonal, you'd have to look straight-through the telescope, which can be tricky and downright uncomfortable when looking at certain areas of the sky. Bending the light collected by the Observer II 70mm telescope at a 90° angle lets you look down into the eyepiece so you can relax and enjoy the view.
    • Use the included Orion Shorty 2x Barlow Lens to double the magnifying power of included eyepieces.
      A 2-power (2x) Barlow lens is an extremely versatile telescope accessory that doubles the magnification of any eyepiece installed. Using the included Shorty 2x Barlow with the 10mm eyepiece in the Observer II 70mm Equatorial Refractor bumps its viewing power from 70x to 140x, and boosts the 25mm eyepiece's magnification from 28x to 56x when used with the telescope. What's more, you can use the compact Shorty 2x Barlow with any other 1.25" eyepieces you already have, or any you purchase in the future.
    • Use the RedBeam Mini LED flashlight to see in the dark without disrupting dark-adapted vision.
      You don't need a big flashlight to read star maps or see inside your accessory case at night. The included 2.5"-long Orion RedBeam Mini Flashlight does the job perfectly, emitting night-vision friendly red LED light. Red light won't disrupt your eyes' dark-adapted vision, so this flashlight lets you check charts and accessories while keeping your eyes primed for viewing celestial gems through the Observer II 70mm Equatorial Refractor Telescope. Includes batteries and a handy key-ring.
    • Use the Orion MoonMap 260 to learn more about the lunar features you see in the telescope.
      With locations and names of over 260 features on the Moon such as craters, mountains, valleys, "seas" and more, the included Orion MoonMap 260 is a great tool for beginning astronomers. This detailed map will even show you where various spacecraft have landed on the Moon's surface! The MoonMap 260 can be used to plan what to look at on the Moon, and to learn the official names of all the interesting lunar landscape features you see in the Observer II 70mm Refractor Telescope.
    • The Orion Star Target planisphere is a useful star chart wheel for any day of the year.
      This circular star map lets you dial-in the month and day you're observing the sky, so you can see exactly which constellations and stars will be visible if skies are clear. Using the Orion Star Target is a great way for starters to plan their first stargazing sessions with the Observer II 70mm Equatorial Refractor since you'll know just where to point the telescope!
    • The Orion Telescope Observer's Guidebook will introduce you to the wonders of the night sky.
      This book will help you explore amazing celestial objects including planetary, emission and reflection nebulas; double and multiple stars; open and globular star clusters, the Andromeda Galaxy, and more. With a full page of information dedicated to each interesting object, author Richard J. Bartlett leads you on a detailed tour of the night sky as he describes over 60 fascinating astronomical objects that can easily be seen with a small telescope.

    The Observer II 70mm Equatorial Refractor Telescope is a great choice for those just getting started in astronomy. It is lightweight and compact so it's easy to carry to your observing location, be it out on the lawn or an hour's drive into the hills. The telescope offers optical performance that will keep any observer entranced, evening after evening. Get in on the fun and get an Orion Observer II 70mm Equatorial Refractor Telescope today!
