What will the telescope show?
You can get excellent views of the Moon with this telescope, and also view a range of other objects in the sky. In common with other similar instruments, it is best suited to use at fairly low magnifications, particularly when several people want to look at the same object through the telescope in succession. This is because the mounting is not driven so as to track objects through the sky. Higher magnifications increase the speed with which objects move through the field of view, and also give a dimmer image, so it is best to start with low powers.
  • The Moon is revealed in detail, with its craters and mountains easily visible and providing a wealth of detail for study
  • The major features of the giant planets Jupiter and Saturn can be seen. Jupiter shows its belts and zones and its flattened disc which is a result of its rapid rotation. With care, some finer detail may be visible. Its four major moons, discovered by Galileo, can be seen and their movements tracked over a period, or even over a matter of an hour or so in the case of the fastest moving. The rings of Saturn are easily visible.
  • Pleiades

    From even a city location, the telescope will reveal star clusters that are invisible to the unaided eye. From a darker location, a number of nebulae (gas clouds) and the closer galaxies such as the Andromeda Galaxy are visible, though these require more care to find than bright objects such as the Moon.
