A refracting telescope works just like a magnifying glass. It uses a convex glass lens (to bend light and bring it into focus. This lens is thicker in the center than it is toward its edges, which bends the light more at the edge of the lens than light coming through the center. This allows all of the light to come together at a focus point. The point of focus is where the image is created.
Alt-azimuth mount is a simple two-axis mount for supporting and rotating telescope about two mutually perpendicular axes. One vertical and the other horizontal.
Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the telescope. Rotation about the horizontal axis varies the altitude (angle of elevation) of the pointing direction.
The accessory tray allows you to keep eyepieces, lens extensions or even a hot drink in one place. Thanks to the tray you will have quick access to everything that you need during a night sky observation.
