Best telescope for beginners
The most important aspect of any telescope for beginners is its aperture, the diameter of its objective - lens or a mirror. The bigger the aperture the better – image will appear bright and sharp. your telescope should have at least 2.8 inches (70 mm) aperture.
Magnifications depend on the eyepieces you put into telescope. Top useful magnification is 50 times your telescope’s aperture in inches, or twice its aperture in millimeters. How to know the magnification you get from your eyepiece? Simply divide the focal length of the scope by that of the eyepiece.
Pay close attention to the weight of the scope you’re considering buying. A really large scope requires either a permanent observatory or friends to help you assemble it for each observing session.
Telescopes are divided into three types: refractors, reflectors, and catadioptrics.
Refractors have a long tubes with a large lens in front and an eyepieces at the back. These telescopes are well suited to those who wish to have a “pick up and go” instrument. They can provide the finest images attainable with a given aperture, but also refractors are the most expensive instruments.
Reflector is the best-value scope, but it needs cleaning and realignment of the mirror time after time. If you are not interested in astrophotograpfy – choose Dobsonian. This is a refelcor on a very simple, very rugged mount.
Catadioptrics (compound) have both lenses and mirrors. They are very compact and transportable.
The telescope is useless unless it’s on a stable mount: altitude-azimuth or equatorial. Altitude-azimuth mount moves the scope up-down and left-right. An equatorial mount makes the tracking of celestial objects easier as the Earth turns. drive motor can do this automatically. Computer-controlled “go-to” mount allows to direct the scope to any object in the computer’s database.
At the end – price. Best scopes for beginners cost $400 or more.
You will see:
- Moon with its cratered terrain;
- Venus phases;
- Jupiter satellites and Saturn rings
- Double stars (Mirar, Albireo)
- Globular clusters (M13 in Hercules, M11 in Scutum);
- Open cluster Pleiades (M45);
- Ring nebula (M57) and Orion nebula (M42);
- Andromeda galaxy (M31).
