Refractor Telescope Description:

A refractor telescope is the traditional expectation of what a telescope looks like. It features a long tube with an objective lens located at the front and the eyepiece at the back. Focusing takes place at the rear of the telescope whilst the front objective lens refracts the light gathered to form a crisp and high contrast image in the eyepiece. Refractor lenses are a rugged design with a sealed tube, making this the perfect choice for those new to star gazing and younger users.  Refractors excel at moon and planetary observations, however are also capable of viewing stars.


Altazimuth Mount Description:

An Altazimuth mount or “AZ” is a simple design using two axes to support or rotate the telescope, restricted to up, down, left or right motions. Its simple design makes this mount easy to use and allows a quick manual adjustment by the user. The simplicity of use makes this mount a great choice for a beginner’s telescope, or as a secondary instrument for quick and easy use.  The limitation of this type of mount is if you are planning to view one object all evening, constant small adjustments in all directions will be needed, as the stars and planets rise and set in the sky like the sun.
