So you want to get involved in astronomy? How do you choose a telescope? What do I need? These may be questions that you have asked yourself prior to purchasing a beginner telescope and you may have searched the internet or the library for what to get to begin your search of the celestial body.

Beginner telescopes are important decision since making the wrong choice may lead to a lack of interest in astronomy. While you may see a variety of telescopes as you leave the store, making your choice in choosing a beginner telescope should be an educated one and not spontaneous to avoid making the wrong choice and thus losing interest and wasting money.

Beginner Telescopes

Choosing a telescope is a difficult process for the novice and if you do not make the right choice you may lose interest or worse your child may lose interest in the whole process. Choosing a telescope that allows for optimal viewing of celestial bodies and entering the amazing world of astronomy is an important step since putting too little money or too much money into the process. Since knowledge is important in choosing I suggest that you research your product and understand what you want to view in the night sky.

Telescopes are a semi-expensive investment, while low-end telescopes are available they may not provide you with the astronomical view that you hope for, thus for a little more money you could be impressed with the results. Making the choice of course is based upon what you can afford and what your level of interest, also if you are purchasing for a child or yourself.

Children are fickle and may lose interest and you would be selling your beginner telescope on EBay or in a yard sale if they lose interest quickly, especially if the results of the viewing of stars are less than stellar; so make the choice wisely and you could be upgrading to a bigger telescope

Beginner telescopes choice is an important step for budding astronomers and thus making the choice in telescopes for yourself or another in your family a step that could make or break you, choosing based upon research and perhaps the skills of others interested in astronomy can become instrumental in your choice of telescopes. Whether you choose a high end, medium priced or low end telescope is a personal choice and only you can make that choice.

Microscopes are mechanical devices used for viewing objects and materials so minute in size that they are undetectable by the naked eye. The process conducted with such an instrument, called Microscopy, uses the combined schools of optical science and light reflection, controlled and manipulated through lenses, to study small objects at close range.

The basic microscope consists of several complex and interrelated parts: a cylinder that provides a necessary space of air between the ocular lens (eye piece) situated at the top and the objective lens fixed at the bottom, hovering close to a stage containing an optical assembly on a rotating arm and a centered hole through which a light shines from a solid U-shaped stand beneath. Magnifying values for the ocular range through X5, X10, to X20, while the values for the objective lens has a broader span: X5, X10, X20, X40, X80, and X100. These values provide the observer with a spectrum of possible distance orientations and degrees of sharpness as are necessary for viewing and analysis.

Several different kinds of microscopes exist, each having particular features:

Optical Microscope: The first ever created. The optical microscope has one or two lenses that work to enlarge and enhance images placed between the lower-most lens and the light source.

Simple Optical Microscope—uses one lens, the convex lens, in the magnifying process. This kind of microscope was used by Anton Van Leeuwenhoek during the late-sixteen and early-seventeenth centuries, around the time that the microscope was invented.

Compound Optical Microscope—has two lenses, one for the eyepiece to serve the ocular perspective and one of short focal length for objective perspective. Multiple lenses work to minimize both chromatic and spherical aberrations so that the view is unobstructed and uncorrupted.

Stereo Microscope: This is also known as the Dissecting Microscope, and uses two separate optical shafts (for both eyes) to create a three-dimensional image of the object through two slightly different viewpoints. This kind of microscope conducts microsurgery, dissection, watch-making, small circuit board manufacturing, etc.

Inverted Microscope: This kind of microscope views objects from an inverted position than that of regular microscopes. The inverted microscope specializes in the study of cell cultures in liquid.

Petrographic Microscope: This kind of microscope features a polarizing filter, a rotating stage, and gypsum plate. Petrographic Microscopes specialize in the study of inorganic substances whose properties tend to alter through shifting perspective.

Pocket Microscope: This kind of microscope consists of a single shaft with an eye piece at one end and an adjustable objective lens at the other. This old-style microscope has a case for easy carry.

Electron Microscopes: This kind of microscope employs electron waves running parallel to a magnetic field providing higher resolution. Two Electron Microscopes are the Scanning Electron Microscope and the Transmission Electron Microscope.

Scanning Probe Microscope: This kind of microscope measures interaction between a physical probe and a sample to form a micrograph. Only surface data can be collected and analyzed from the sample. Types of Scanning Probe Microscopes include the Atomic Force Microscope, the Scanning Tunneling Microscope, the Electric Force Microscope, and the Magnetic Force Microscope.

Science wouldn’t be what it is today without the microscope, as this device is the primary instrument by which the world and all of its elements are measured and assessed. It is with the microscope that we take a look inside of ourselves so we can learn and understand who we are and how we work.

A telescope is a viewing instrument that utilizes the refraction or reflecting of light rays and allows for images to be brought closer. This capturing of light is accomplished through a component that is called the objective.

The objective is that part of the telescope which, through the captured light, provides an image of the object that is being viewed. Typically, the objective is either composed of a set of lenses or a concave mirror.

Now, think about the possibilities of utilizing liquid to mirror reflections back to our vision. The concept of a liquid mirror would be similar to the experience of looking at your image in a pool of water. However, a liquid mirror telescope would be used to peer into the depths of space. At first glance the concept of a liquid mirror telescope seems like something that is a far-fetched and very futuristic.

However, the future is now as astronomers realize the potential of employing a liquid mirror telescope to take the place of a concave mirror that is typically found in a reflecting telescope.

History Of A Liquid Mirror Telescope

Isaac Newton in the 17th century was the first individual to go on record about the possibilities of a liquid mirror telescope. In his studies, he realized that when liquid is spun it forms a natural concave bowl-like shape. This spinning liquid would provide the same shape of the concave mirrors that are used in a reflective telescope.

Unfortunately, his idea was ahead of its time. The reason being is that the electric motor had not been invented. The electric motor would have been needed to provide the rotation required to give the liquid its concave form.

The first documented case of a liquid mirror telescope being used was in 1909. However, it wasn’t until 1982 that a physicist by the name of Ermanno Borra modified the design to improve the performance of the liquid mirror telescope. One such telescope is located in British Columbia, Canada.

Structure Of A Liquid Mirror Telescope

Fortunately, today, all of the needed technology is available and has, in fact, brought the practical use of a liquid mirror telescope in to practice. Specifically, the liquid that is used is 30 liters of mercury. This mercury is poured into a concave dish that is built in segments. The dish itself is manufactured from a durable plastic coupled with polyester. The frame that holds the dish is a light metal.

The Process

In order to form the shape required to optimally provide the reflection needed, the dish begins to spin. The spinning speed is about 7 revolutions per minute. This speed is maintained so that the proper distribution of the mercury occurs.

Advantages And Disadvantages

The only disadvantage that has been demonstrated in the use of a liquid mirror telescope is the need for the dish to remain parallel. This is obviously due to the fact that if tilted the liquid would flow gravitationally to the end that is tilted downwards.

The advantage is that the area of reflection is extremely large. This larger area provides a greater capacity to capture more light which adds to the visibility of the object being viewed. In turn, this larger area of reflection allows for greater distances in the galaxy to be observed.

Whether you are a hunter, bird watcher, astronomer, or other user of binoculars, the tips in this article can help you choose the best quality binoculars for your purposes. Following are three major quality factors you should examine before buying a pair of binoculars.

First of all, you’ll need to choose the magnification power of your binoculars. The most common magnifications range from 7-12. More is not necessarily better, though. The higher the magnification power of your binoculars, the more noticeable the shaking of your hands becomes. For most uses, 8x is a good magnification to choose. If you go over 10x, you should consider getting a tripod.

Second, you’ll need to choose the objective diameter for your binoculars. All other things being equal, the larger the objective diameter, the brighter the image you see through the binoculars. For most uses, look for a objective diameter that is five times the magnification power. So if you have a pair of binoculars with 8x magnification, they should have an objective diameter of 40. A pair of binoculars with these specs is generally called “8×40”. If you plan on using your binoculars in low light conditions, you may want get an even higher objective diameter, such as 8×50. Do keep in mind that a larger objective diameter will generally increase the size and weight of the binoculars.

Thirdly, you should pay attention to the coating of the lenses on your binoculars. The coating cuts down on reflected and fragmented light inside your binoculars, and so increases, the brightness and clarity of the image. There are four terms generally used to describe the lens coating. Here they are, in order for least desirable to best: coated, multi coated, fully coated, fully multi coated.

No matter what you plan to do with your binoculars, paying attention to these three points when making your purchase will greatly increase your chances of getting the perfect pair of binoculars!

When we were children we were often taught that we could wish upon the first star that we saw in the evening sky. After that wish was made and if we believed hard enough our wish would come true. Eventually, our childhood fantasies gave way to fact as we became more educated. This education was accomplished through astronomy classes, space exploration and other educational means.

The word astronomy is comprised of two Greek words. The Greek word astro means star shaped or star and pertains to outer space. The word onomy literally means the study of. Therefore, astronomy is the study of the stars.

One of the major tools that assists amateur and professional astronomers in understanding and respecting the galaxy is the astronomy telescope. When looking to purchase a good astronomy telescope there are a number of factors that you can keep in mind. First, of all consider some practical suggestions, remember it is about the diameter of the lens, and make sure your telescope has a solid stand.

Practical Suggestions

Before you purchase your astronomy telescope it is important to conduct your research. One way of conducting this research can be accomplished by accessing the Internet and learning more about telescopes. Some of the questions that you should endeavor to answer surround what features to look for in a telescope, approximate cost, recommended brands, etc.

Another practical suggestion, before you purchase your astronomy telescope, is to “test drive” a telescope. This can be accomplished by joining an astronomy club. Often these clubs will have a stargazing event which will allow you to peer through the telescopes owned by the various members.

Another way of conducting research, prior to purchasing an astronomy telescope, is to ask the members in the club as to what telescope they would recommend. The key is education. Listen for the features they recommend, brand names, the diameter of the lens, price, etc.

Also, you may come across a member of the club who is considering the purchase of a new telescope. If so, you may be able to purchase their used telescope.

Diameter Of The Lens

When considering the purchase of an astronomy telescope it is important to remember what is the key feature surrounding your purchase. That key feature should focus on the diameter of the lens of the telescope and not its advertised magnification.

This is because the diameter of the lens equates to the amount of light that can be received by the telescope. Therefore, the larger the diameter of the lens the more light that is captured. This in turn allows for the image that you are viewing to become more visible.

Solid Base

Another very important feature when considering the purchase of your astronomy telescope is to ensure that it has a solid base. Generally, these bases or mounts are tripods.

It is important that when the telescope is mounted on these bases that the telescope does not shake or move. Obviously, any movement by the telescope, when peering into space, will distort the image being viewed and provide a negative experience.

Binoculars are one of the essentials when it comes bird watching. They take a tiny speck and turn it into something you can not only see but identify as part of your bird watching experience. There are a number of different brands and styles that are available on the market ranging from a few dollars to thousands of dollars a pair depending on what you are looking for.

For basic bird watching, a standard set that you find in any hardware or sporting goods store will probably be appropriate to your needs. They are only a few dollars and usually hold up fairly well. Binoculars are always rated with two numbers. The first indicates the magnification power that the binoculars has. The second number indicates the front lens diameter.

Usually these are written in the following manner 7×23. This set of numbers indicates that the binoculars have a magnification of seven with a diameter of 23 millimeters on the front lens. The magnification power of the binoculars that you want depends on how far you plan to be away from the birds you are planning to watch. If you are planning to watch just around your neighborhood at birds that may be in trees or on the ground, then a lighter magnification will probably work. For those that want the ability to spend a large amount of time watching birds interact naturally or where the required distance is significantly greater than watching normal everyday birds, you will want to get a stronger magnification.

There are binoculars that have a single level of magnification, these are usually the basic style that allow simply a slight amount of focusing. There are then the styles that allow you to be able to alter not only the focus of the lens but also the level of magnification, allowing you to adjust between objects that are closer and farther away without having to have additional sets of binoculars.

When purchasing binoculars, check them out and make sure they are not too heavy. Some pairs can be hard to handle or hold up for longer periods of time, so this is another factor that you should consider if you are in the market to purchase a pair of binoculars. There are a number of lightweight models that offer a full range of features without being hard to handle. This is essential if you are planning to carry them around while trekking looking for birds or planning on sitting for long periods of time holding them up.

Nothing ruins a bird watching trip more than ending up not being able to spend the time you want or get to where you want due to the weight of the equipment. Some of the features to look for is scratch resistance on the lens, and a way to carry them other than in your hand or around your neck. This will help to not only protect them, but keep them out of the way while you are making your way to your location of choice.

If your hunting go quits shooting straightaway, with 100yard groups having deteriorated from 1 inch to four or five, you’d return remedial actions-such as cleaning the bore, checking the telescopic sight and mounts, and checking the bedding. And, if wholly else failed, you’d likely issue it to a gunsmith. A similar position exists once binocular that once provided crisp, clear images no longer live up to your expectation. As a scribe whose forte is writing approximately optics, I am often asked to examine other hunters’ field glasses that purportedly “aren’t as goodness as they secondhand to be.” Sometimes I tin fix the problem and sometimes not, merely usually I tin can tell what’s wrong. Once, subsequently being handed a opera glasses by an Alaskan caribou huntsman, I looked done it and found the survey to be anything simply clear.

Refractor telescopes are some of the oldest telescopes available, utilized at around the beginning of the 15th century and still around today the refractor telescope is quite possibly one of the oldest telescopes in use today. Made up of concave lenses that allow the light to be refracted and images to appear bright and larger than looking at it with the normal eye the refractor telescope can greatly aid in seeing stars, planets and moons.

These telescopes are made up of convex lenses and an eyepiece lens similar to binoculars, these refractors gather light and bend it in order to view objects at a distance, which is particularly useful when looking at stars and the night sky Refractor telescopes may seem complicated and are made up of lenses that are concave and refract the light.

The telescope come in a variety of versions; the Galilean telescope which is named after its creator was one of the first versions and was improved upon by Johannes Kepler with the Keplerian Telescope, which is a refractor telescope that utilized a convex eyepiece as opposed to a concave of the Galilean model. The decades and centuries since have observed newer inventions and different lenses, with the achromatic refractors invented in the mid 16th century and later with apochromatic refractors.

Pros and Cons of Refractor Telescopes

I stated previously that refractor telescopes have been around a long time and with that comes a definite plus since there is a definitive ability to know what the pros and cons of the telescope. These telescopes have obviously come a long was since the 15th century yet the technology has increased to a point in which the refractors have improved yet the size of refractor telescopes pose a problem in the fact that the larger the refractor lens the more chance that it can have defects or begin to sag.

While technology continues to grow and there is no telling where refractor lenses in telescopes will go to in the future one thing for sure is that refractor telescopes have been around for centuries and thus show no decline in their use by many of astronomers. So no matter what telescope you choose to utilize to view the universe or neighborhood, you can not dismiss the value of the refractor telescope and the impact that its utilization has had on astronomy and the search of the skies.
