Product Details

  • Orion's StarSeeker IV 150 mm GoTo f/5 Newtonian Reflecting 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 large reflector optical tube with a 750 mm focal length and moderate f/5.0 focal ratio, the versatile StarSeeker IV 150 mm Reflector collects a ton of light with its 6-inch aperture, parabolic reflecting optics for very bright, wide-field views. The entire telescope setup weighs 22.3-pounds for easy transport, whether you're heading down the road or just out to the backyard.

    Following a simple two-star alignment process, the Orion StarSeeker IV 150 mm 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 150 mm GoTo Reflector locates a target for you to explore, the single-arm Alt-Azimuth 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-Inch eyepieces are included with the StarSeeker IV 150 mm GoTo Reflector. The included 23 mm wide-field eyepiece provides 32.6x magnification in the 150 mm reflector optical tube, and the 10 mm ocular yields a higher magnification, 75x view through the telescope. Each included eyepiece has a wide, 60-degrees apparent field-of-view to show you more of the target object and its surroundings.
     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 150 mm GoTo Reflector lets you explore the skies with push-button 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 Alt-Azimuth design provides attached telescopes with 360-degrees of Azimuth motion and 90-degrees of Altitude motion for horizon-to-zenith pointing. A quick-release narrow dovetail saddle makes telescope attachment nice and easy. The StarSeeker IV 150 mm 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 150 mm Reflector 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 150 mm to explore the rewarding hobby of astrophotography. (Cameras and SteadyPix accessories sold separately.)


    Each StarSeeker IV telescope is powered by 8 internally stored AA user supplied batteries. A 12V DC auto-lighter plug is included for use of optional 12V DC field batteries.

    Very good

    After using this telescope for a while, I would say it is very good. I have gotten detailed views of Saturn with its rings but mars is only a bright circle. I haven’t seen Jupiter yet though and there are great views of the moon. It is not too bad for deep sky viewing considering I live in a very light polluted area. I have seen a few galaxies but with very little to no detail but you can see them. I haven’t seen any nebulas so I am hoping to see one soon. Overall, if this is your first telescope, it is worth it. But if you are looking for deep sky images, I suggest you get something with an 8 to 10 inch reflector. Also to start the alignment process press enter 2 times... it took me a little while to realize this lol.
