The Celestron AstroMaster refractor telescope is ideal if you are looking for a dual-purpose telescope for both terrestrial and celestial viewing
The AstroMaster Series produce bright, clear images of the Moon and planets. It is easy to see the moons of Jupiter and the rings of Saturn with every one of these fine instruments. For views of deep space objects like galaxies and nebulae, we recommend the larger aperture and light gathering ability of the Newtonian reflectors. Each telescope is ready to use within minutes with their no-tool set up.
The AstroMaster mount is a German equatorial type and comes with two slow motion control knobs that allow you to make fine pointing adjustments to the telescope in both Right Ascension and Declination axes, also referred to as RA and DEC.
This telescope comes with a simple motor drive to allow the telescope to track celestial objects as they move across the sky. This easy-to-install RA motor drive compensates for the Earth’s rotation, so the telescope tracks a star’s movement through the night sky from east to west. When the telescope mount is properly polar aligned and the RA drive is attached and running, the user need only make occasional adjustments in declination (Dec) to keep an object in the eyepiece for long periods of time. The Celestron single-axis motor drive runs on a 9V battery, so there are no cords to get in the way. The drive can be used in either the Northern or Southern Hemisphere. To change hemispheres (reverse the motor’s direction), simply by flip the N/S switch on the face of the motor drive. It is also simple to change the speed of the motor. A “Speed Rate Regulator” knob is located just under the power indicator and can be turned in either direction to slow down or speed up the motor. Since solar system objects like the Moon and planets move through the sky at different rates than deep-sky objects do, this gives you the ability to match the motor’s speed to the particular type of object you are observing.
Also included is a smartphone adaptor. With its light, rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 34mm. The additional magnification provided by the eyepiece allows your phone to capture great images of the Moon and planets. This adaptor installs easily by placing the smartphone over the telescope eyepiece and tightening the knobs to securely lock your phone in place. The adaptor accommodates most phones with the case on, but some large and/or bulky phone cases (including folio style cases) may need to be removed for the phone to fit in the adaptor.
Accessories include a 20mm and 10mm eyepiece, erect image diagonal, and a finderscope. The two eyepieces offer different magnifications for low and high powered views. Also included is a smartphone adaptor for taking images of the Moon and planets.
