Why A Telescope Mount Is A Necessity For Stargazing


If you have ever tried looking through a telescope without a telescope mount to steady your equipment, you understand the difficulty of focusing on a set object in the night skies. Compound that problem with a heavenly body that is actually moving across the sky and you realize that it is almost impossible to track this object. There is no doubt, stability of your telescope is key to enjoyable stargazing.

Purpose of a Telescope Mount

A telescope mount provides a stable platform for your telescope, whether it is a refracting telescope, reflecting telescope, Dobsonian telescope, or catadiotric telescope. A telescope mount will ensure that your viewing of a celestial body is not interrupted by unexpected movement. It also determines how you will position your body relative to the telescope to view the night?s sky, determining how comfortable you will be over any extended period of stargazing.

Types of Telescope Mounts

Altazimuth telescope mounts are generally used on a Dobsonian type telescope. These telescopes look like a large canister and are mounted on a chassis that provides limited mounting capabilities. With this type of mount, the telescope can be adjusted in up and down or left and right positions. This range of movement in a telescope mount is generally fine for the beginner and intermediate astronomer.

Equatorial mounts are more advanced and allow for greater movement to coincide with the movement of planet Earth. As good as this sounds, there is a level of skill required by the user. The user will need to understand the planet movement and be required to make minor adjustments to the telescope mount. This type of mount is usually reserved for higher quality telescopes, so it is really geared for the intermediate to advanced astronomer. However, with a little experience and practice, the mount could be used by most stargazers.

In this hi-tech era, computers have become an integral part of astronomy and are used to move and track heavenly bodies. Well, an advanced telescope mount, though expensive, is available that provides this kind of computer tracking and superior viewing options. This mount even facilitates the viewing through the computer monitor as well as the eyepiece, with a few clicks of your mouse moving the mount into position.

Choosing the Right Mount

In choosing the right mount, you must first determine what the intended use of the telescope is. Other considerations are the skill level and specific needs of the operator. Determining the type of terrain the mount will be used on will dictate the stability requirements. And, of course, your astronomy budget will play a major role in what type of telescope mount you will purchase.

Choose a mount that will allow for a comfortable body position for times of extended viewing. Nothing can ruin a stargazing experience faster than being required to contort your body in unnatural positions to get a satisfactory view of your desired object.

So, to choose the right telescope mount, take the time and effort to research the different brands of telescope mounts and the various quality levels available. Then, and only then, choose the one that best suits your needs and falls within your budget limits. It can make the difference between a comfortable, enjoyable stargazing experience and a cramped, short-lived outing.

Celestron Firstscope 114EQ 114mm Reflector Telescope



Celestron Firstscope 114EQ 114mm Reflector Telescope
The Firstscope 114 EQ is a high quality, economical telescope with superb optical systems housed in a glossy black metal tube. The equatorial mounts are quite stable, with setting circles and slow motion controls on both axes for easy, smooth tracking. Strict adherence to Celestron's tough quality standards for manufacturing, assembly and testing ensures that each telescope performs well.

The 114mm (4.5 inch) Newtonian equatorial telescope is the most popular size telescope for the more serious beginning or intermediate level astronomy enthusiast, and for good reason. The large light gathering power of this 4.5 inch telescope makes it ideal for deep-sky observation of galaxies, star clusters and nebulae, as well as lunar and planetary observing. This makes for a very useful and versatile instrument that can take an observer from the very first time looking through a telescope's eyepiece, through years of observing interesting subjects near and far in the night sky.

Reflectors
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.

    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 114 EQ.

    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.
