Refractor- It is most commonly used and traditionally designed telescope. The telescope has a lens or mirror in the front to gather light and capture an image. It is a little expensive but the cost depends on the aperture, so a small refractor can be good option as a telescopes for beginners.
Newtonian reflector- It can be viewed using an eyepiece.Larger apertures are available but at the expense of portability.
Catadioptric - These telescopes use a mixture of lenses and mirrors and are of two types, the Schmidt-Cassegrain and the Maksutov-Cassegrain. The important feature of these telescopes is their compact tubes, which is half reflector and half refractor. These features are not always found on telescopes for beginners, however.
Alt Azimuth and Equatorial- the mount telescope comes in two types: the Alt Azimuth and equatorial. They can be helpful for terrestrial and field view. A Dobsonian is a type of Alt Azimuth. It is made for large reflectors whereas Equatorial are designed to track objects with small adjustment.
