FirstScope 70 models are powerful optical instruments that have 100 times the light gathering ability of the naked eye. This ability allows the FirstScope 70 to deliver images 37% brighter than those produced by a 60mm refractor telescope. The objective lens is designed to yield the finest images available in this class of optical instrument. The accessories are all made of glass with metal construction, to ensure good image quality. These telescopes have all glass components, coated optics and smooth functioning mounts, with the added benefit of slow motion controls on the mount for easy adjustments. The FirstScope 70 telescope tubes are glossy black aluminum.
| This is a refractor telescope. Refractors (also known as a dioptrics) capture light with a lens at the front of a long tube and send it to an eyepiece at the other end. They look, in other words, just like what most people think of when they hear the word "telescope." |
Refractors offer--potentially, at least--the cleanest images of any telescope design. They are simple and reliable (the sealed tube is maintenance-free), and are good for both celestial and terrestrial viewing.

The German equatorial mount features setting circles and slow motion controls on the R.A. and DEC axes. These controls will enhance your viewing experience by simplifying both locating and tracking objects. When you're looking for a telescope offering a bit more versatility and control than the altazimuth models, these are the telescopes to consider. These telescopes yield breathtaking views of the moon, Saturn with its ring structure, Jupiter and its belts, and hundreds of deep-sky objects including: galaxies, nebulae and star clusters. Add an optional solar filter and you can observe activity on the sun.

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 70.
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.
Observing the Planets
Other easy targets include the five "naked eye" planets of our solar system, so called because they can be spotted in the night sky by the unaided eye. You can see Venus go through its lunar-like phases. Mars can reveal a host of surface detail and one, if not both, of its polar caps. Youll be able to see the cloud belts of Jupiter, perhaps even the great Red Spot. In addition, youll be able to see the moons of Jupiter as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate power, as is Mercury. All you need to know is where to look. Most astronomy publications indicate where the planets are in the sky each month.
