Orion StarSeeker IV 127mm GoTo Mak-Cass Telescope

  • Our StarSeeker IV 127mm GoTo Mak-Cass telescope presents a winning combination of motorized object-location technology and great optical performance 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 compact Maksutov-Cassegrain optical tube with an extra-long 1540mm focal length and f/12.1 focal ratio, the conveniently portable "Grab-and-GoTo" StarSeeker IV 127mm Mak-Cass collects a lot of light with its 5" aperture objective lens for bright views, while its long focal length provides very sharp resolution at high magnifications. The entire telescope setup weighs just 22.2 lbs. for easy transportability.

    Following a simple two-star alignment process, the Orion StarSeeker IV 127mm telescope can guide you to interesting sights on any clear night with its GoTo database of over 42,000 objects. A handy, built-in "Tour" mode feature of the included GoTo hand controller makes it easy for anyone to explore the wonders of starry skies, no matter how familiar or unfamiliar you are with the night sky. Once the StarSeeker IV 127mm GoTo Mak-Cass locates a target for you to explore, the single-arm altazimuth mount's internal motors will automatically track the object's apparent motion and keep it centered so you can enjoy the view as long as you wish.

    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.

    This complete GoTo telescope setup includes a thorough assortment of useful accessories:

    Two wide-field 1.25" eyepieces are included with the StarSeeker IV 127mm GoTo Mak-Cass
    The included 23mm wide-field eyepiece provides 62x magnification in the 127mm Maksutov-Cassegrain optical tube, and the 10mm ocular yields a very high-magnification, 154x view through the telescope for close-up 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.

    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 Mak-Cass places the eyepiece you're using in a comfortable position for nighttime stargazing of the skies above.

    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.

    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.

    The StarSeeker IV GoTo mount and its slanted, single-arm altazimuth design provides attached telescopes with 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 Mak-Cass to explore the rewarding hobby of astrophotography. (Cameras and SteadyPix accessories are not included and are sold separately.)

    Each StarSeeker IV telescope is powered by 8 internally stored AA batteries (not included). A 12V DC auto-lighter plug is included for use of optional 12V DC field batteries.
