Take a guided tour of the cosmos without leaving your backyard! The value-packed StarSeeker IV 127mm GoTo Mak-Cass Telescope Kit is a great setup for beginning amateur astronomers since it's loaded with so many great accessories and features a complete GoTo telescope system.

The Orion StarSeeker IV 127mm GoTo telescope presents a winning combination of powerful optical performance and motorized object-location technology at an unbelievably low price. This smart GoTo telescope will lead you and your family on a guided tour of the stars on any clear night. Featuring a long, 900mm focal length Maksutov-Cassegrain (Mak-Cass) optical tube with an f/11.2 focal ratio, the StarSeeker IV 127mm GoTo Mak-Cass delivers detailed, high-magnification views of the Moon, planets, and bright deep-sky objects. The entire telescope setup weighs just 19 lbs. for easy transportability.

The SynScan GoTo hand controller included with the Orion StarSeeker IV 150mm telescope contains a database of over 42,000 stars and deep sky objects, which you can explore with pushbutton ease. No knowledge of the night sky is necessary! Select from intuitive object menus or try the "Deep Sky Tour" mode to visit a selection of the evening's best objects. Once a desired target is pinpointed, the StarSeeker IV mount's internal motors automatically track it to keep it centered in the eyepiece.

What's more, the StarSeeker IV mount is now Wi-Fi enabled, which allows you to control it wirelessly from your smartphone or tablet instead of the cabled hand controller! Just download the FREE SynScan Pro app to your iOS or Android device to enjoy wireless GoTo control! The app sets up a local Wi-Fi network between your phone and the mount, so no internet connection is needed in the field. Hey, you use your phone for everything else — why not use it to explore the night sky with your telescope, too?

This fourth generation StarSeeker telescope features dual optical encoders on each axis of motion which allow you to move the telescope tube either manually by hand, or electronically by using the directional arrows on the GoTo hand controller. To save time, battery life, and reduce motor wear, you can manually point the telescope towards the general area of a target object, then engage the tube lock and use the hand controller to let the GoTo mount finish the fine-centering of the object electronically.

The StarSeeker IV 127mm GoTo Mak-Cass Telescope Kit comes with a great selection of useful accessories:

Two wide-field eyepieces

Two wide-field 1.25" eyepieces are included with the StarSeeker IV 127mm GoTo Mak-Cass.

The included 23mm wide-field eyepiece provides 67x magnification in the 127mm Maksutov-Cassegrain optical tube, and the 10mm ocular yields very high, 154x magnification views through the telescope for closer inspections of starry skies. Each included eyepiece has a wide, 60 apparent field-of-view to show you more of the target object and its surroundings.

90 degree star diagonal

Use the included 90 star diagonal to view the night sky comfortably.

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 90 star diagonal that comes with the StarSeeker IV 127mm GoTo Maksutov-Cassegrain places the eyepiece you're using in a comfortable position for nighttime stargazing of the skies above.

EZ Finder II

The Orion EZ Finder II reflex sight makes it "EZ" to center alignment stars.

Use the included EZ Finder II reflex sight to help center initial alignment stars when performing the two-star alignment required for accurate GoTo performance. This non-magnifying sighting device superimposes a tiny, LED-powered red dot, focused at infinity, on the sky. After a simple alignment procedure, the red dot shows exactly where your telescope is pointed.

Hand controller

Let the computerized GoTo controller guide you on a tour.

The StarSeeker IV 127mm GoTo Mak-Cass lets you explore the skies with pushbutton ease thanks to its GoTo hand controller. With a vast database of over 42,000 celestial objects including stars, double stars, galaxies, nebulas, star clusters, and more, the included computerized GoTo hand controller will become your tour guide to the skies. The built-in "Tour" mode will show you great sights on any clear night.

Moon Filter

Use the Moon Filter that comes with the telescope kit for great lunar views.

Improve your telescopic explorations of the Moon by using the included Orion 13% Transmission Moon Filter. The threaded filter is easy to install on the included 23mm and 10mm eyepieces, and its neutral-density filtration will help enhance contrast of craters, mountains, and other interesting lunar features. The 13% transmission filter also helps reduce the bright glare of the Moon to make observations more comfortable.

Deep Map

Use the included DeepMap 600 Folding Star Chart to plan deep sky observing adventures!

The StarSeeker IV 127mm GoTo Mak-Cass Kit includes the popular DeepMap 600 folding star chart. This "road map" of the cosmos will tell you just where to look in the night sky to find interesting objects to explore in the powerful StarSeeker IV telescope. Color-coded symbols identify more than 500 galaxies, nebulas, and star clusters — including all 109 Messier objects — as well as some 100 of the most interesting double and variable stars. DeepMap folds up just like a road map for easy packing, and it's printed on durable dew-proof material for worry-free outdoor use.

Moon Map

The Orion MoonMap 260 makes it easy to learn about 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 Orion MoonMap 260 included with this telescope kit is a great tool for all amateur astronomers. The whole family will enjoy using the MoonMap 260 to properly identify all those craters and other lunar features the Moon Filter helps accentuate.

AC-to-DC Adapter

Keep your StarSeeker IV telescope powered all night long.

This complete telescope kit also includes an AC-to-DC Adapter so you can keep your StarSeeker IV telescope's motors powered from a 110-volt wall outlet. The handy adapter is especially useful for long stargazing sessions, since you won't have to worry about running out of battery power. The AC-to-DC Adapter features a 6-foot long cable, and easily attaches to optional extension cords.

The StarSeeker IV GoTo mount and its slanted, single-arm altazimuth design provides 360 of azimuth motion and 90 of altitude motion for horizon-to-zenith pointing. A quick-release narrow dovetail saddle makes telescope attachment nice and easy. The StarSeeker IV 127mm features an upgraded cylindrical leg stainless steel tripod that is much sturdier than previous models and adjusts in height for comfortable use. Tripod stability is further enhanced with the included dual-purpose spreader plate/accessory holder, which keeps the tripod rigid and provides a handy area for stowing idle eyepieces and accessories.

Since the StarSeeker IV 127mm Mak-Cass can locate and track celestial objects with its motorized GoTo system, you can use it along with a camera or smartphone to take impressive pictures of the night sky. Capture stunning snapshots of the Moon, planets and more by attaching a dedicated astrophotography camera, or a combination of an Orion SteadyPix accessory and your own point-and-shoot camera or smartphone to the StarSeeker IV 127mm to explore the rewarding hobby of astrophotography. (Cameras and SteadyPix accessories sold separately.)

The StarSeeker IV 127mm GoTo Mak-Cass Telescope can be powered with household electricity using the included AC-to-DC Adapter, or you can use 8 internally stored AA batteries (not included). A 12V DC auto-lighter plug is included for use of optional 12V DC field batteries.
