You can see a galaxy that is 2.5 million light years from where you’re standing…with just your eyes.

Grab a decent pair of binoculars and you can see craters on the Moon.

It’s no wonder why millions of people have latched on to the millions of wonders that are to be seen far into space.

And many of these people do so right from the comfort of their front porch, back yard, or even a bedroom window.

They’ve taken the first step to exploring man’s final frontier.  The cosmic exploration that people have been writing, drawing and wondering about for millennia.

The first step in this beautiful and mind-captivating journey is to get a decent telescope.

Different Types of Telescopes

There are 3 main different types of telescopes: Refracting, reflecting, and catadioptric. Each of the types has its advantage and disadvantages. Let’s look at how each telescope type works and what they are best at.

Refracting Telescopes

Refracting telescopes are a simple type of telescope and very recognizable. The designs of these telescopes are very simple. A refracting telescope has a lens at each end of a tube.

The major advantage of refracting telescopes is its simple design. This design makes these telescopes simple to use. They are also very reliable since the optics have been permanently aligned and fixed.

The major disadvantage of a refracting telescope is that they are very heavy. They are also are hard to transport and store as they need longer bodies. Refracting telescopes can also be very expensive, as the lenses can be costly to make.

Reflecting Telescopes

Reflecting telescopes are similar to refracting telescopes but are a little more complex. A reflecting telescope uses mirrors internally to reflect the light into the telescope’s eyepiece.

The major advantage of reflecting telescopes are that they are portable and compact, which makes them easy to move around. These telescopes are also a more affordable option.

The major disadvantage of reflecting telescopes is that the mirrors need to be re-aligned regularly. The mirrors can slip out of their alignment from the smallest bumps and knocks. Even the temperature can cause the mirrors to become unaligned. In some reflecting telescopes, the mirror has a small defect, causing the light not to be reflected correctly.

Catadioptric Telescopes

Catadioptric Telescopes are a hybrid of refracting and reflecting telescopes, as they use both lenses and mirrors to form the images.

The major advantage of catadioptric telescopes is that most are extremely portable and compact. Since the optics use both mirrors and lenses, catadioptric telescopes has the benefits of both.  They are great all-purpose telescopes.

The major disadvantage of catadioptric telescopes is they suffer from a loss of light, due to the positioning of the telescope’s secondary mirror. However, this is not very noticeable in most models. They can also have image shifts or jumps in the focusing. This is caused by the primary mirror being shifted during focusing.

Those are the three main types of telescopes on the market. Each of the different types of telescopes has their own advantages and disadvantages. These advantages and disadvantages make each type of telescope unique and work a little bit differently. The make and model of the telescope can also have its own pros and cons, as the information above is an overview of the telescopes. No matter what type of telescope you prefer, there are many options on the market.
