With its substantial 90mm (3.5") aperture and versatile f/6.7 optics, the StarBlast 90mm Travel 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 StarBlast 90mm Travel Refractor Telescope.

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. The StarBlast 90mm Travel Refractor includes a 90 star diagonal for comfortable nighttime viewing, a 25mm eyepiece for 24x views, 10mm eyepiece for more powerful 60x views, and an EZ Finder II reflex sight to help aim the refractor.

The included Beginner Barlow Kit is a great combination of accessories for anyone beginning a hobby of amateur astronomy and includes the powerful Orion Shorty 2x Barlow Lens, as well as the useful Orion Beginning Stargazers Toolkit.

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 StarBlast 90mm AZ bumps its viewing power from 60x all the way to 120x, and boosts the 25mm eyepiece's magnification from 24x to 48x when used with the 90mm refractor. 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.

The Orion MoonMap 260 makes it easy to learn about the Moon's craters, spacecraft landing sites, and more!

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 whole family will enjoy looking at the Moon with the StarBlast 90mm refractor telescope, then discovering the names of the craters and other features you've seen in the 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 StarBlast 90mm refractor, since you'll know just where to point the telescope!

The useful Discover the Stars guidebook will introduce you to the wonders of the night sky.

This gets our vote as the best guidebook for beginning stargazers. The heart of the book is two sections of big, two-color sky charts. The first section features 12 charts that show the entire visible sky each month, accompanied by text that points out each month's sky attractions and constellation mythology. The second section comprises 23 charts of smaller regions of the sky, which highlight objects observable with small instruments. Softbound, 119 pages.

Use the included RedBeam Mini LED flashlight to see in the dark without disrupting your 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 StarBlast 90mm telescope. Includes batteries and a handy key-ring.
