The Celestron AstroMaster 114mm aperture reflecting telescope is ideal if you are looking for a telescope for astronomy. It provides bright, clear images of the Moon, planets, star clusters, and more for great nighttime viewing.
The AstroMaster mount is a manual 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. A simple motor drive is included 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.
You can download Celestron’s Starry Night Software, with its 10,000 object database and printable sky maps, and learn about the night sky, celestial objects, and how to plan your next observing session. Celestron Starry Night Software is the premier astronomy software package on the market, providing resources and knowledge to view our solar system and beyond.
