Three Types of Telescopes - What are the Advantages

!±8± Three Types of Telescopes - What are the Advantages

Refractors, Newtonian reflectors and Catadioptrics
are the three main types of telescopes. All these
different types have the same purpose, but each
telescope design does it differently. Collecting
light and bringing it to point of focus so it can be
magnified and examined with an eyepiece is their
goal.

Of the different types of telescopes the refractor
is the telescope most people think of when they
think of astronomy. This type of astronomy telescope
is easy to use and reliable due to the simplicity
of design. It requires little or no maintenance. Its
great for looking at the different types of lunar,
planetary, and binary stars.

Newtonians are a type of telescope, which is also
known as catoptrics. This type is different from
the other telescopes because it has the lowest
per inch of aperture compared to refractors and
Catadioptrics, because lenses are more expensive
to produce than mirrors, especially in medium
to large apertures. Newtonians deliver very bright
images and are low in optical aberrations.

Catadoptric telescopes are the most popular type
of instrument, with the most modern design,
marketed throughout the world in 3 1/2 and larger
apertures. Its very good for looking at different
planetary, lunar, and binary stars. If you like to
take photos with your telescope this type of
instrument is excellent for deep sky observing
or astrophotography with fast films or CCD's.

The Lunar Secrets of the Moon

!±8± The Lunar Secrets of the Moon

A persons horoscope is heavily influenced by the Moon. The placement of the Moon and the link between the Sun and the Moon is one of the major influences. It describe a persons emotional feelings, your ability to nurture and it affects your mood and your reaction to the moods of others.

However there is a lunar secret that is very important to take into consideration when your horoscope is being analyzed. When you look at the Moon to determine the mood of a person you have to look for the cycle the Moon were in at the time of birth of the person.

Was the Moon, New, Crescent, First Quarter, Gibbous, Full, Disseminating, Last Quarter, or Balsamic Moon. These are called "the Lunar Cycle" and they can help you understand the moods of a person. These lunar cycles represent subtle feminine energy and power in your chart.

By finding the placement of the Moon in your chart you will be able to clarify why a person may have certain moods and often get into similar situations without realizing why. For instance if your Moon were in the New Moon phase which last about three and a half days then your mood would generally be one of emergency.

The New Moon is for planting and creating. So the kind of mood for this person would be one of hopefulness for the future and generally perceive the world as a place of possibilities and a life of joy.

The next lunar cycle is The Crescent Moon and the person with the Moon in this position has a strong urge to overcome pressure and inertia of the karmic past and by working through these issues they often discover personal limits and their special purpose. This position is from three and a half to seven days after New Moon.

The Gibbous Moon phase is ten and a half to fourteen days after New Moon and with this position you have an intense energy of overcoming past and present issues. You believe that whatever decision have been made must now be lived with. This is a time of testing and adjustment, flexibility and perseverance are qualities that need to be nurtured.

Third Quarter or Full Moon is when it is opposite the Sun. This position has to do with your relationships of the heart, marriage and is a constant feeling of insecurity in which you may wonder if your partner is really happy with you. Learn to be happy within yourself and do not let your partner control your moods.

Next is the Disseminating phase which is three and a half to seven days after the Full Moon. This is a time where you begin to understand your inner struggle and are able to let go of them because you now understand what is underneath them.

The Last Quarter is seven to ten and a half days after full Moon. This position represents the harvest and meaning of understanding and whatever does not harmonize with the growing consciousness and understanding can not be accepted.

The last phase is the Balsamic which occurs during the final eight of the entire cycle ten and a half to fourteen days after the Full Moon. The general mood of this cycle is release and a period when emptying is necessary before a new cycle can begin. The Balsamic Moon people are old souls who have lived before and are here to complete and put into use those gifts they have already attained hence fulfilling a past vision.

Constellations - Libra - Names of Stars

!±8± Constellations - Libra - Names of Stars

The two stars within the Libra constellation, Alpha, along with Beta Librae, are both astronomical highlights meriting seeing with the naked eye, field glasses and scopes. Furthermore, these two Libran stars are what makes up the romance and secrets of Libra.

Alpha Librae is a colourful twin typically depicted as radiant by viewers. The stars are conventionally characterized as bright white and radiant yellow and Beta Librae has for many periods been specified as the unique single star perceptible in the celestial sphere. Beta Librae for many eras has been referred to as the exclusive green star observable to the naked eye.

The majority of observers and many astronomers conceive there are no perceivable green stars. The agreed wisdom is that the human optical structure will translate ranges climaxing at concise wavelengths as white with a blue shade and ranges culminating at long wavelengths as white with a reddish-orange hue. However, characteristically green stars are practically never referred to. But seasoned astronomers understand that Beta Librae has subsisted as a green star over several eras.

In spite of the fact that astronomers understand the two clearest stars of Libra as Alpha and Beta, the stars have been studied for so long that they have favoured titles. Furthermore, their favourite names are two of the most interesting in the heavens.

Alpha Librae is called, "Zubenelgenubi," and Beta Librae is known as, "Zubeneschamali." These are both derive from the Arabic language and from a very peculiar age when the Roman empire controlled the known world. Those two designations touch on one of the biggest puzzles of the zodiac. The designation Zubenelgenubi stands for 'The Southern Claw' and Zubeneschamali designates 'The Northern Claw.' At some spot throughout the supremacy of Rome, the academics of the period agreed to modify the zodiac and for rationales as yet unknown decided to remove the group of stars Libra by uniting the stars of Libra with the stars of Scorpius.

Libra continues to be unequalled amid the zodiac signs and it is the only zodiac symbol that is lifeless, if you analyse all the other characters you will see they are persons, creatures, bugs and so forth - only Libra is not a living object.

Meade Telescopes For the Home

!±8± Meade Telescopes For the Home

Are you looking to buy your first telescope? You likely have looked around, and have been wondering if Meade telescopes are any good, this article will not help you in deciding, but also help you in choosing a model that will ultimately allow you to have the best time in astronomy!

In this article, you will soon discover:
* About Meade And Their Telescopes
* About Buying Your First Telescope
* 2 Buy Computerized Or Manual

* About Meade And Their Telescopes
Meade telescopes come from a corporation called - Meade Instruments Corporation. In 1972, John Diebel started Meade as a small mail order telescope company. They used to sell small reflecting telescopes and accessories.

In 1978 Meade started manufacturing Schmidt-Cassegrain telescopes. Meade Instruments Corporation has also produced larger telescopes, which can even be found in some observatories! Meade is now the leading telescope manufacturer, with its telescopes being found all around the world!

Over the years, Meade has improved there telescopes, and every new model that comes out has new features or advancements that are useful to amateur astronomers and professionals alike.

* About Buying Your First Telescope
Buying your first telescope can be one of the most exciting things you do! Imagine suddenly you have gone from having a planet with over 6 billion people, to having also the universe with its infinite range of objects!

To get the most out of astronomy, you will need to invest. Not everyone has the budget that NASA has, such as they did with building the Hubble Space Telescope! However, even with a small budget of only a few hundred dollars, you can get some great views that the universe has to offer.

You can find telescopes for sale in many places. The problem is that there are not that many stores that specialize in telescopes. The alternative is mail order or even better, to buy online. I have lost count of the amount of telescope stores that are available online. This makes buying your first telescope much easier.

* 2 Buy Computerized Or Manual
There are 2 types of telescope - reflecting telescopes and refracting telescopes. Both do a good job, however, refracting telescopes become expensive as they get bigger. A cost effective alternative is the reflecting telescopes, which offer great views of deep space objects. I find refractors are great for planetary viewing.

Today we are blessed with technology. Telescopes have taken advantage also, and there are offerings from Meade, Celestron and Orion that have computerized versions which enable you to simply click a few buttons and the telescope zooms to the destination! Talk about making astronomy both fun and simple!

The choice you make whether to go for a GoTo computerized telescope or to buy a manual telescope, will come down to your needs. For example do you want to be adventurous and learn how to navigate the heavens or would you prefer to navigate with the aid of a computer, which makes it simple as click and zoom!
