The Celestron FirstScope Series of telescopes is designed with the first-time telescope buyer in mind. Offering exceptional value, these scopes feature compact and portable designs with ample optical performance to excite any newcomer to the world of amateur astronomy. Each telescope has its own design characteristics to help you choose which is best for you. The smaller FirstScopes feature refractor optical designs while the larger apertures feature Newtonian reflector optical systems.
| | This is a reflector telescope. Reflectors (also known as Newtonian reflectors or catoptrics) capture light with a mirror at the bottom of a tube, which sends the image to the eyepiece at the top of the tube.
First-time telescope users sometimes have difficulty with the idea of looking through the side of a telescope, but the big draw for reflectors is that they are by far the cheapest to manufacture--and thus offer the best value--of all telescope types. They also generally have zero chromatic aberration.

The FirstScope 76 is a fine instrument for the beginning observer. It offers many of the advantages of the Newtonian design at a 3" aperture. The superb optics of this telescope offer dazzling images of the moon; Saturn and its rings; Jupiter, with its belts and moons; and hundreds of deep-sky objects, including galaxies, nebulae and star clusters. The optical tube is glossy black. This model uses the German equatorial mount with setting circles and slow motion controls on both the right ascension (R.A.) and declination (DEC.) axes. These features make it easier to locate and track objects.
While observing, you'll notice that as the earth rotates on its axis, stationary stars appear to move across the sky. Thus, due to the earth's rotation, the object you're viewing will drift out of view in both axes, over time. A telescope on an equatorial mount can be aimed at a celestial object and guided with the slow motion controls to follow the object across the sky and keep it in the field of view of your telescope.

Moon viewing 101
The moon is often one of the first celestial objects a beginner will look at through his or her telescope. Here are a couple hints for you once you get your hands on your new FirstScope 76.
Often, it is tempting to look at the Moon when it is full. At this time, the face we see is fully illuminated and its light can be overpowering. In addition, little or no contrast can be seen during this phase. One of the best times to observe the Moon is during its partial phases (around the time of first or third quarter). Long shadows reveal a great amount of detail on the lunar surface. At low power you will be able to see most of the lunar disk at one time. The optional Reducer/Corrector lens allows for breath-taking views of the entire lunar disk when used with a low power eyepiece. Change to higher power (magnification) to focus in on a smaller area. Choose the lunar tracking rate from the NexStar's MENU tracking rate options to keep the moon centered in the eyepiece even at high magnifications.
Product Description
The Celestron Firstscope 76EQ is a fine instrument for the beginning stargazer, offering many of the advantages of Newtonian telescope design and a 3-inch aperture. Newtonians (also known as catoptrics) usually use a concave parabolic primary mirror to collect and focus incoming light onto a flat secondary (diagonal) mirror that in turn reflects the image out of an opening at the side of the main tube and into the eyepiece. The superb optics of the Firstscope 76EQ offer dazzling images of the Moon; Saturn and its rings; Jupiter, with its belts and moons; even galaxies, nebulae and star clusters. MA Eyepiece (70x) and Focuser Star Pointer Finderscope Sturdy, Adjustable Aluminum Tripod with Accessory FirstScope 76 EQ Standard Accessories - 1-1/4 20mm (35x), 10mm (70x) Eyepieces, Star Pointer Finderscope, Equatorial Mount, The Sky L1 CD ROM
