The Celestron Astromaster 90AZ is a powerful and simple to use refractor telescope. The telescope includes a 90mm optical tube, an alt-azimuth mount and a pre-assembled tripod. Also in the box is the Celestron NeXYZ 3-axis smartphone adapter that will allow you to take images through the telescope (smartphone not included).
 
The Astromaster 90AZ offers erect image optics which will allow for views of the sky and on land in the correct orientation. With a dovetail mounting system, the telescope only takes a few moments to set up and pack down, for ultimate useability. The pan handle included on the mount design allows for smooth accurate pointing, and the starpointer finderscope will make it easy to target objects in the night sky. This telescope is great for viewing the craters and other detail on the moon, and planets - with the moons of Jupiter and rings of Saturn viable targets.
 
The included NeXYZ 3 axis smartphone adapter allows you to use your smartphone camera not only on this Astromaster Telescope, but most telescopes/binoculars/microscopes that use eyepieces from 35mm to 60mm in diameter. An included microscope adapter ring allows connection to standard 25mm microscope eyepieces. The platform accomodates a huge range of smartphones, usually with most phone cases still installed. The unique 3 axis design allows for centering adjustment left and right/up and down over the eyepiece and the distance between the phone's camera lens and the eyepiece.
 
Refractor Telescope:

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:

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.
