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. Thanks to this impressive upgrade, the StarSeeker IV 127mm Mak-Cass will not lose its GoTo alignment if you reposition the telescope tube manually, or accidentally bump into a tripod leg during an observing session. 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.
