More about the product

The 120/900 Sky-Watcher ED apochromat has exceptionally good optics, color correction is excellect despite the 2 elements design, it even overperforms some triplet lenses. A multi-purpose telescope providing much more power than the similar but smaller on Moon, planets and even on faint galaxies. Compared to the 80mm model, the resolution is increased by 1,5x while it gathers 2,25x more light.

For photographic use also recommended. To image fainter objects use the Sky-Watcher 0,85x reducer/corrector to ensure sharp stars even at the edges. The focal length is also reduced while the scope becomes a faster one and fainter objects can be photographed with shorter exposure times.

Physically the tube length equals to the length of the 100mm modell, in terms of diamater this one is slightly bigger and slightly weights more. The focuser is a 2" Crayford one with microfocuser.

The telescope can be purchased in different configuration, at least EQ5 or higher mount is recommended, depenging on expectations and use. But the telescope and the mount together and save 12% on the price of the mount.

For the GoTo version we highly recommend the Skywatcher Wi-Fi unit (SynScanWifi), with which you can control your telescope via smartphone or tablet. Just plug the Wi-Fi unit into the hand controller slot and download the free App (Android or iOS) - it is ready to use.
