203MM APERTURE NEWTONIAN REFLECTOR TELESCOPE EQ 800X F

Style, Functionality & Strength

The heavy duty German Equatorial Mount (EQ), sets this telescope apart from others on the market. Only a EQ mount allows you to track an object smoothly across the sky.

Right ascension and declination markers and the ability to micro adjust the position of the telescope make this telescope simple and accurate.

Whether you are just exploring the night sky or following a star chart don't use anything but an (EQ) Mount.

You are bidding on a brand new Newtonian short tube Equatorial Reflector Telescope. $999.00 RRP

Perfect for Observing Galaxies and Nebular's

This telescope has a Aperture of 203, and a huge Focal Length of 800.

This is a high quality precision Telescope which is designed for looking at deep space objects like planets, galaxies, stars etc. It comes complete with a heavy duty German Equatorial Tripod or mount, enabling easy smooth tracking of objects across the sky.

Modern Telescopes come in two basic types.

The Reflective Telescope, which uses mirrors

The Refractive Telescope, which uses glass lenses.

Both types accomplish exactly the same thing, but
in completely different ways.  There are more
sophisticated telescopes available but almost all the
telescopes on eBay fall into the two types above.

Refractive Telescope

Reflective Telescope

Basically a telescope is made up of 3 components.

• An objective lens (in refractors) or a primary mirror (in reflectors)
• A tube or housing, and
• An eyepiece lens.

The objective lens or primary mirror collects light from a distant object and brings it into the tube where it is gathered and blended into focus. It is then bent into a bright point know as a focal point, the image is then magnified through an eyepiece and brought to your eye.

When considering what telescope you need you should first ask what you would use it for. Stargazing, looking at the planets, moon or sun or looking at terrestrial objects like birds and whales.
Refractor telescopes are most suitable for viewing terrestrial or land-based objects, while reflectors are best suited to looking deep into the solar system and objects like nebulas and galaxies. Both types are suitable for looking at the moon, sun and planets. By now you will probably seen there are many telescopes, spotting scopes and telescope accessories available on e-bay.  So how do you pick one? 

Most modern telescopes are manufactured in China and can look identical to each other.  These because the telescope housings (the tube) are manufactured by one company and the internal components are manufactured by another.  The best way to find out about the quality of a particular telescope on eBay is to ask the seller questions about the primary mirror or objective Lens.  If they are unwilling to give you information or the information is vague then stay away.  Bottom line you get what you pay for.  As a guide Reflective telescopes start at about $100.00 and go up to about $1000.00, Refractive Telescopes start at about $400.00 and go up to about $5000.00.  Most of the Refractive telescopes sold on eBay are in fact toys. 

There are four main areas to think about.

1. Aperture refers to how much light the objective lens or primary mirror collects, the more the better. Think of it like a digital camera, the more dots there are in a photo the better the image and the more it can magnify. The higher the aperture the more light is gathered and the clearer, sharper and better the image will be. Buy as high a aperture as you can.

2. Focal length is the distance required by the objective lens or primary mirror to bring all of the light collected to one point (Focal Point). Generally, long focal length telescopes are capable of delivering height magnifications than short focal lengths. Don’t make the mistake of thinking that this means that longer tubes are better as shorter tube telescopes use folded light paths, which provide larger focal lengths. They are also easier to transport but are more expensive.

3. Tripod choice is often over looked when considering a telescope and yet is just as important and the scope itself. There are two basic types of tripods or mounts, Alt-azimuths and German Equatorial (EQ). Alt-azimuths are most commonly found on toy or cheaper telescopes. They consist of two axes of rotation, horizontal axis and a vertical axis. Alt-azimuths are cheap to make and have no fine movement control features, which make zooming in on even the biggest targets difficult.
   German Equatorial (EQ) Tripods or mounts also have two axis of movement (right ascension and declination). However, instead of being orientated up and down, it is tilted at the same angle as the earth’s axis of rotation. These tripods allow for smooth tracking of celestial objects across the nights sky, and are essential if you want to take photos. German Equatorial Telescopes also come with varying levels of micro adjustment barrels, which are essential in effective stargazing.

4. The telescope's magnification, its ability to enlarge an image, depends on the combination of lenses used. The eyepiece performs the magnification. Since any magnification can be achieved by almost any telescope by using different eyepieces, aperture is a more important feature than magnification.
