If you are new to astronomy telescopes, knowing what type to purchase is key in receiving the ultimate experience in viewing the world. There are two different classes of telescopes, a reflecting telescope and a refracting telescope. Curved mirrors dictate the center point found with reflecting telescopes and often distort the image by creating streaks of light or smudges from the initial object. A refracting telescope uses glass in the place of mirrors and is able to focus on a small point, thereby being more compact in size.
Astronomy is a fascinating subject for those of all ages. Children are often drawn to the stars because they offer a dimension that is new and different than what is seen on earth. Selecting a refracting telescope that can aid in pinpointing many of the constellations of the universe can begin a great hobby or possibly a future in astronomy.
The original design of the refracting telescope has changed little since first used in 1608 in the Netherlands. Galileo of Venice first laid claim to astronomy telescopes in 1909 but they were in operation far before his version became popular. The combination of a primary glass lens plus a secondary lens located in the eyepiece help to gather more light that enhances viewing. More modern astronomy telescopes have a prism encased that gives even better reflection of the object.
When looking at the wide choice of astronomy telescopes, quality is always a major factor. Models with 70 mm lenses are standard for beginning hobbyists and begin around $100. As one progresses into the interest of the galaxy, more advanced models are available that feature 120 mm lenses and present strikingly clean views of planetary subjects with special optical glass. Computerized pointing and printing is also possible for further study. Advanced astronomy telescopes can cost as much as $2500 or higher, depending on your needs.
Enjoying the deep wonders of the universe can be an exciting way to spend as a family. Grab your refracting telescope and head out to the country where the night sky is filled with hundreds of attractions. One popular movement today is the attaching of a camera and telephoto lens onto the equatorial mount. This is referred to as Piggyback Astrophotography. This procedure takes some experience in photography but offers great views of the Milky Way, Nebulae or Gas Clouds for viewing after you have packed up and gone home.
Having and evolving an interest in astronomy can be a lifelong adventure in understanding the universe and astronomy telescopes can become a way to cultivate this interest. If you are a beginner, start with an inexpensive refracting telescope and see where it takes you. Be ready for those rare occasions when comets race close to our planet or just wanting to check out a closer look at the stars on a brilliantly clear night.
