The larger the aperture is the more light comes in the telescope and the brighter your image will be. The reflector's open tube means that dust and dirt are more likely to accumulate on the optical surfaces even if you're careful to cover the tube in storage, and this will mean occasional cleaning. Using a telescope for viewing planets will give you more detail and a clearer view of the planets. This makes it a long scope but gives it the skills needed to make great work of planet watching. However, 6" of aperture is best used for brighter objects like planets, the moon and brighter Messier objects. This makes some refractors great for astrophotography, but they are generally the very expensive 'apochromatic' lenses and generally out of reach of new starters. The newest crop of Go To scopes include their own Global Positioning System devices to at least tell you and the telescope exactly where you are and what time it is, making setup a little easier.

Binoculars can be a good first step, but they won't show any detail on the planets and limited detail on the Moon. The Equatorial Mount permits one to turn a telescope in the opposite direction from that which the Earth is rotating, at the same apparent speed as the Celestial objects are moving. For convenient observing, or for astrophotography many mounts will accept the option of or may include a battery powered drive motor to permit automatic rotation of the telescope. Astronomers may make "Target of Opportunity" proposals, in which observations are scheduled if a transient event covered by the proposal occurs during the scheduling cycle. Some people complain that it is plastic, but it does not make it work poorly because of it. Click on image to enlarged the view and read the print , bytes.

As a result, an experienced observer might enjoy deep sky objects in an 80 mm refractor, while a beginner with a light bucket next door is still struggling to find the Orion Nebula. Space telescopes were proposed as early as The type, and quality of the mount and its drive system will determine what if any distractions from observing there may be, and if one will be provided the ability to become involved with astrophotography.

Technical Specification
Description: So we are not saying that in time one can not pursue this work with an XT-8, but it will need to be moved onto a suitable tracking German Equatorial Mount to be successful in astrophotography such as shown at right. Notice how the physical length of this f6 telescope is about six times the diameter. An alt-az mount operates like a tripod's pan-and-tilt head, moving the scope up-down in altitude and left-right in azimuth. So more than ever before, the inexperienced shopper may have to do some research to determine not only what they wish to buy but also the competence, and character of that organization which he or she is dealing with.
