Product Description

With its substantial 90mm (3.5") aperture and versatile f/7.3 optics, the Orion 10029 StarBlast 90mm altazimuth refractor is the great grab-and-go telescope you've been looking for. Not only will you get great views of the Moon and its hundreds of intriguing craters and canyons, but this compact travel telescope will also provide awesome views of comets, Jupiter's cloud bands, the four largest Jovian moons, and Saturn's amazing ring system, even from brighter urban locations.

Since the StarBlast 90mm is so portable and lightweight at 13.5 lbs. when fully assembled, it's easy to take on the road to your favorite dark sky site, or bring along on the next family campout or road-trip. From reasonably dark skies, this portable performer grabs very nice views of emission nebulas like the Lagoon (M8), the Orion Nebula (M42), as well as dying stars like the Ring Nebula (M57), globular clusters like the Great Cluster in Hercules (M13), and gorgeous open star clusters like the Double Cluster in Perseus and the glittering Pleiades (M45). From a dark sky site with inky black skies, there are literally hundreds of deep sky objects you can track down with the affordable Orion 10029 StarBlast 90mm altazimuth refractor and a star chart of astronomy program such as the included free special edition of Starry Night.

The included altazimuth mount is easy to operate, and gives the StarBlast 90mm telescope a stable foundation. The mount's convenient slow-motion controls make it easy to manually track celestial objects as you view them over extended periods.

This portable performer comes with a host of great astronomy accessories. The StarBlast 90mm Travel Refractor includes a 90° star diagonal for comfortable nighttime viewing, a 25mm eyepiece for 26.4x views, 10mm eyepiece for more powerful 66x views, an EZ Finder II reflex sight to help aim the refractor, and free Starry Night Special Edition astronomy software.

For optional use during the day, you can use a 90° 1.25" Correct-Image Star Diagonal (#8787, sold separately) to have the StarBlast 90mm Refractor display a correctly oriented, non-reversed daytime view. (The included star diagonal yields an image that is upright, but reversed left-to-right). Not compatible with correct image diagonals #7216 or #8754.

Portable, affordable, and simply adorable, the Orion StarBlast 90mm Travel Refractor is the beginner-level telescope you've always wanted!
