Sky-Watcher 70/900 is a very well designed lenticular telescope (refractor) with a 70mm lens diameter and 900mm focal length. It allows for advanced visual observations of planets and the Moon, showing a significant amount of details on the surfaces of these objects. It works great as a "planetary spotter" - especially in urban and suburban areas - but it is also a basic observation equipment for around nebular objects. Under good observational conditions, it can reveal about one hundred nebulae, galaxies and star clusters contained in the Messier and NGC catalogs.
In addition, it works well as a strong observation telescope, which can be put on a larger balcony or terrace.
It also has a built-in focuser with a diameter of 1.25 inches, which allows the use of any glasses made in this standard. The whole is a perfect solution for both beginners and advanced observers, guaranteeing a very competitive price.
The telescope's EQ1 paraglider montage is a known quality that guarantees good stiffness, enabling observation at high magnifications. The light, but strong aluminum height-adjustable tripod is easy to carry and at the same time stable, while the accessory shelf and the precise micromovement mechanism on hand-operated scrolls complete the set.
The telescope has been additionally equipped with a 90 ° SLR connector for convenient observation of objects high in the sky and giving a terrestrial image (not reversed) in the observation of terrestrial objects

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.
