A Rudimentary Guide to Refractive Telescopes



Perhaps the oldest type of telescope is the refracting telescope that has been in use since the early 15th century. The design was good and has been improved upon since then but essentially a refracting telescope is still a refracting telescope.

The refractor has a set of convex lenses that allow the images presented to the viewer to take on a larger shape and be bigger and brighter to the perspective of the viewer. This makes them especially useful for viewing the stars, planets and other celestial bodies.

The telescopes are made up of a series of convex lenses that feed an image through an eyepiece lens much like you would find in a set of binoculars. These harness the principles of refraction to bend light and better view distant objects. This has allowed for many great observations of the night sky. While their design amy seem complex, the idea is fairly simplistic and just requires a few properly shaped lenses.

There are also various versions of the refracting telescope that have been invented and popularized for different reasons. The Galilean telescope is named after the famous scientist whose insights into the universe challenged the “truths” of his time. This was one of the first refracting telescopes in history. The Keplerian refractor was also named after another noteworthy man of science which changed the Galilean concave eyepiece to a convex eyepiece.

The various designs and styles would be changed and improved much over the next few centuries. The achromatic refractor would be introduced in the mid-16th century with the more impressive apochromatic refractors being invented years after.

Pros and Cons of Refractor Telescopes
As the technology that supports the refractor telescope continues to evolve, there have been many advancements made in the telescope. While the technology continues to advance, the issue of size has become a problem. The fact is after a certain size, the telescope will have a greater chance of defects in the construction that retard the function and performance.

While we are not sure how the refracting telescope will advance from here, we do know that many of the world’s greatest achievements were visualized through a refracting eyepiece. This type of telescope has been in use for centuries and will continue to do so as the years continue.

No matter which type of telescope you choose to use, you are sure to have a unique view of your neighborhood and the universe. Never forget the importance of the famed refractor and how much our word has benefitted from the brilliant design.

Bushnell Telescopes – Why They Are The Best



Many people are fascinated with the skies and the stars. Gazing upwards to see where the planets are and the locations of various constellations they are turning to the best telescopes that are available on the market today. Quality optics along with precision engineering have made Bushnell the best name in regards to telescopes.

When choosing your telescope, you’ll want to first determine the main use you’ll be using it for. Will it be for night viewing? Or will you want to have an aperture that is easier to carry around? Will you want one that isn’t too heavy or will a heavier one work for you? There are many models of telescopes on the market today and you can select from a variety of them. You’ll love enjoying the stars once you choose the right model for your needs.

Beginners may prefer a refractor telescope. These are ideal as they are easy to assemble and they offer up a variety of uses and they’re lightweight. If you’re planning to look at the night sky or during the daytime hours, these are an ideal choice. Reflector telescopes are heavier and larger and ideal for finer detail and night viewing, especially if you’re going to remain in one location. Larger apertures offer you a better view of the night skies.

Other important features are that you’ll want to make sure it has a solid base. Typically, these bases are on tripods and very stable.

If you want a very stable viewing experience you’ll want a mounted telescope. Bushnell telescopes are easy to mount.

It’s important to remember that a mounted telescope won’t move or vibrate which means you’ll have a clearer view. Of course, any movement of a telescope is going to distort your image. It may even ruin the experience if your telescope moves.

If you’ve decided that it’s time to become more serious about your star gazing, you may wish to consider a computerized Bushnell Telescope. These allow you to set up the coordinates and set them to specific times of the day. You can automatically find what you’re looking for and use the telescope easily. This is ideal for beginners who are unsure of where specific constellations are. Bushnell offers a computerized mount that works very well to keep it on the constellation you set it on.
