Celestron AstroMaster 90AZ Telescope

The Celestron AstroMaster 90AZ Telescope is a great-value full-featured telescope that will take star-gazing beginners through to a wide-ranging knowledge of the night sky and it can also be used for terrestrial observations.

The erect image optics mean that what you see through the telescope is the right way up and this makes the AstroMaster 90AZ able to fulfil a dual role exploring landscapes, cityscapes, seascapes and so on as well as celestial objects.

It is simple and quick to set up this telescope and so, depending on cloud conditions, you will soon be able to view such features of the night sky as clear, bright images of the Moon and the planets plus smaller details such as the moons of Jupiter and the rings of Saturn.

The SkyX software supplied with the telescope will allow you to find out the location of celestial objects that interest you or identify those you see through your eyepiece but whose names you not know.
