Cons of the Telescope

Mirrors can suffer from coma when not aligned properly

Technical Details …show more content…

Over time, the alignment of the mirrors can be jostled, and you'll find that there's coma problems with your telescope. It's like using a guitar to learn to play. After some time, it's going to need to be tuned. It's best if you learn how to collimate the telescope yourself. It's not as difficult as you might have been lead to believe.

In Newtonian telescopes there are mirrors that have to be aligned properly to see the night sky. There's a primary mirror and a secondary mirror. All it takes is to find the sweet spot of the focal ratio for the mirrors. You'll need to find the center of the primary mirror to match it to the secondary mirror.

Collimation isn't difficult at all, and you might not even have to worry about it for a very long time. Many customers reported that the Vixen Optics R130Sf Newtonian and Porta II Mount Telescope worked right out of the box.

It's almost guaranteed that over time and use that you'll need to collimate the telescope because the mirrors inside will be shifted slightly out of place. As far as other maintenance, you'll want to be sure that you're using a padded carrying case for the tube of your telescope. This will keep it safe from breaking and prolong the current collimation.

Griffith Observatory: Building Observatories In The World

1388 Words | 6 Pages

Griffith Observatory Did you know that people have been building observatories since the 200s B.C.? An observatory, by definition, is a place or building equipped and used for making observations of astronomical, meteorological, or other natural phenomena, especially a place equipped with a powerful telescope for observing the planets and stars. Human beings have always been interested in the idea of discovering the unknown, and discovering space is no exception. But only through the last few hundreds of years have we really been able to make advances in astronomy due to large telescopes placed in the observatories. Some of the major observatories in the world are the Mauna Kea Observatory, the Arecibo Observatory, and the Yerkes Observatory.

A Success In Space By Cameron Keady: Passage Analysis

533 Words | 3 Pages

Have you ever thought about going into space? In the passage, “A Success In Space By Cameron Keady”, “Comet probe may shed light on Earth’s past”, there is a probe that is set to land on a comet called the Philae Lander. It will land on a comet and will take pictures of the comet, and dig up samples of its surface. The Philae mission was important for scientific research because it took photos and picked up samples, it could reveal secrets about the makeup of comets that we don’t know, and it could help us get better at landing probes on comets. First, it will dig up samples, take pictures, and take photos of the comet, which will help us learn more about comets.

In space we use Right-Ascension and Declination. Right-Ascension is the distance measured along the celestial equator from the equinox to the hour circle of the point in question. When combined with Declination, these astronomical coordinates specify the direction of a point on the celestial sphere. We are also able to use Azimuth and Altitude. Azimuth represents the direction in which the object can be found.

Edwin Hubble's The Realm Of The Nebulae

Looking up at the vast sky with the naked eye, one can see a beautiful display of stars, planets and the Moon. However, the Earth’s atmosphere distorts and blocks electromagnetic radiation, making it impossible for terrestrial telescopes to observe objects, in space, clearly. In his conclusion of The Realm of the Nebulae, Edwin Hubble describes the limitations of space exploration, “With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial.

With only the 200x, 400x, and 800x on the bottom of each image, it says more than any graph or number, that their telescopes are effective. The three images while being funny, also demonstrated their telescopes, showing clear image of the moon, and the flag on the moon. With most advertisements these days stuffing information of their product down the audience throat, it is hard to not appreciate the ethos used in this ad. Having just three images paired with their zoom length and the brand name Orion Telescope on the bottom, the audience can almost see the simple, but effective products made this
