CELESTIAL OBSERVING

Now that your telescope is set up, you’re ready to use it for observing. This section covers visual observing for both solar system and deep-sky objects.

Observing the Moon

In the night sky, the moon is a prime target for your first look because it is extremely bright and easy to find. Although the beauty of the full moon may make it seem a perfect viewing object, in fact, the light reflected from its fully illuminated face 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, such as a crescent or quarter moon. At these times, long shadows reveal a great amount of detail on the lunar surface. At low power, with the standard eyepiece, you’ll be able to see the whole lunar disk at one time. Change to higher power (magnification) with an optional eyepiece to focus in on a smaller area. Keep in mind that the rotation of the earth will cause the moon to drift out of your field of view. You’ll have to manually adjust the telescope to keep the moon centered.

This effect is more noticeable at higher power. Consult a current astronomy magazine or your local newspaper to find out the current phase of the moon.

Lunar Observing Hint

To increase contrast and bring out visible detail on the lunar surface, try using different filters (available through your local Celestron dealer). A yellow filter works well for improving contrast.

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. You’ll be able to see the cloud belts of Jupiter, perhaps even the great Red Spot. In addition, you’ll 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.

70 specifications

The Celestron 70 telescope, specifically the Celestron Astromaster 70, is a popular choice among amateur astronomers and casual stargazers. This telescope is known for its user-friendly design and impressive optical performance, making it suitable for both beginners and those with some experience in astronomy.

One of the most notable features of the Celestron 70 is its 70mm aperture. This size provides ample light-gathering capability, allowing for the observation of celestial objects such as planets, star clusters, and even some of the brighter deep-sky objects. The optical system consists of a refractor design with fully coated glass optics, ensuring bright and clear images.

The Celestron 70 also incorporates a sturdy mount. The manual Altazimuth mount is intuitive and easy to use, making it simple for users to locate and track astronomical objects in the night sky. It is often equipped with slow-motion controls that help with precision tracking. The lightweight design of the telescope allows for easy portability, making it ideal for viewing sessions in various locations, whether in your backyard or at a remote dark-sky site.

Another key technology in the Celestron 70 is its erect image optics, which produce images that are oriented correctly, making it suitable for both astronomical and terrestrial viewing. Users can easily switch between observing the craters of the Moon, the rings of Saturn, or scenic landscapes during the day.

In addition, the Celestron 70 comes with several useful accessories. It typically includes a finderscope that assists users in locating celestial objects, as well as a collection of interchangeable eyepieces to enhance the viewing experience. The included software often provides a great introduction to astronomy, helping users learn about the various constellations and celestial bodies they can observe.

Overall, the Celestron 70 telescope combines affordability with quality, making it an excellent choice for newcomers to astronomy or anyone looking for a reliable scope for casual observation. With its impressive features, robust design, and user-friendly functionality, it caters to the growing interest in stargazing, inviting users of all ages to explore the wonders of the universe.
