Sky-Watcher Star Discovery 150mm Reflector Telescope
The Sky-Watcher 150/750 Star Discovery is a fully automatic telescope ideal for beginners and those who want to get straight to observing. Aligning the mount takes mere minutes with the “Bright Object” alignment mode, and the computerised SynScan system is the ultimate upgrade that allows automatic pointing and tracking of more than 42,000 object in the sky! This means less time spent finding a faint nebula or a distant planet and more time to enjoy observing. Astronomy has never been so easy!
The Star Discovery mount is the upgrade of the Star Explorer, featuring the Freedom Find dual encoder technology. Once aligned, the telescope can be manually pointed anywhere in the sky without losing alignment, giving the user enormous freedom, convenience and flexibility during the observations.
This Newtonian telescope uses diffraction limited mirrors for a superior optical quality. The primary mirror is aspheric (parabolic) and collimable ensuring precise mirror alignment and crisp image quality. The 150mm aperture has 30% more light gathering than a 130mm telescope and 73% more than a 114mm reflector. This means amazing observations of the rings of Saturn, the bands and the moons of Jupiter, the phases of Venus and the polar ice caps on Mars.

|Highest Practical Magnification||300X|
|Light gathering power (compared to the unaided eye)||459|
It collects so much light with its generous 150mm diameter that distant Deep Sky Objects such as the Ring Nebula in Lyra or the Dumbbell Nebula become beautifully visible and globular clusters, such as M13, resolve into a multitude of individual stars at their edges. Planetary observing provides rich detail in images of Saturn, Jupiter, Venus and Mars. The f5 focal ratio means this reflector falls into the class of 'fast' Newtonian telescopes. This telescope is therefore particularly suitable for astrophotography. The light gathering capacity of the 150 is 460 times greater than that of the naked eye alone (with a 7mm fully dilated pupil).
The advantages in a nutshell:
The Computerised SynScan™ AZ hand control allows you slew your telescope automatically to a specific object, or even tour the night sky at the touch of a button!! The user-friendly menu system allows automatic slewing to over 42,900 night sky objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions.
The exciting new Sky-Watcher Star Discovery mount is an upgraded version of the AZ Go-To mount featuring FreedomFind™ dual encoder technology. This allows the telescope, once aligned, to be moved manually or electronically in either axis without the mount losing its alignment or positional information. After moving to a new object, the mount will continue to track it accurately. This gives the user enormous freedom, convenience and flexibility during observational sessions.
