The Celestron Astromaster 90 AZ telescope is a very well designed classic refractor for azimuthal mounting on a steel tripod. The operation of the telescope is always much simpler than the Newton telescope, and the azimuthal assembly is the easiest to use - it allows for the fastest setting of the searched object. This telescope is dedicated to the observation of the moon, planets and the nicest objects of the deep sky. Due to the high contrast of images, characteristic of refractors, it is a telescope recommended for observation in urban areas, typically "planetary".
With this telescope you will see, among others:
• craters on the moon - the result of cosmic collisions
• Mercury's and Venus' phases - evidence that they are moving closer to the Sun than Earth
• Mars shield
• belts in the atmosphere of Jupiter and its four moons - observing the changes in the positions of the moons of Jupiter, we watch the solar system in a miniature
• Saturn's ring
• shields of Uranus and Neptune, planets unknown to the Ancient
• the brightest asteroids, such as Ceres and Westa
• comets - ice lumps traversed by the Solar System
• the color of stars, double stars and variable stars
• the Orion nebula, Andromeda galaxy, the Sagittari cluster, hi chi in Perseus and much, much more.
To carry out the above observations, a little commitment and patience is enough, and the results will be absolutely fascinating.

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.
