Skywatcher MC 150/1800 Fusion-120i
The Skywatcher MC 150/1800 Fusion-120i gives you sharp, high-contrast images without the hassle. You'll see the Moon and planets with crisp detail, while the compact tube can easily travel with you to any observing spot. The long focal length gives you natural magnifications that help you make small structures visible-even if you're still a beginner.

Clear, sharp images without color errors
The Maksutov optic uses a meniscus lens that neatly corrects the light. This keeps your images sharp, even at high magnification. The small secondary mirror provides high contrast so you continue to see fine details on the Moon, Jupiter and Saturn clearly. The 150 mm aperture captures enough light to make globular clusters and bright nebulae visible as well.

GoTo that does the work for you
With the Fusion-120i mount, you don't have to search. You tap an object in the SynScan app, and the telescope automatically puts it in focus. The motors track the object, keeping it neatly centered. You use your own phone or tablet, without cables, via the built-in Wi-Fi. That way you work quickly and intuitively.
Operate the way you want
You can choose: wifi via the app, Bluetooth or the included SynScan handheld controller with more than 42,900 objects. After a quick alignment, everything is ready and you can start right away. You don't need any experience-the app guides you through every step.
Compact, sturdy and easy to carry
The telescope is surprisingly portable. The built-in handle and sturdy construction make moving easy, while the 12 kg payload gives plenty of room for heavier accessories. The Dual-Fit saddle works with both Vixen and Losmandy rails, so almost any tube will fit.
Flexible in use
The internal battery keeps your session running, or you plug in a 12V power supply if you want to look longer. The 2″ scope, star finder and zenith mirror complete it. All you have to do is choose your favorite eyepieces.
