Telescopes are a type of optical instrument. They use lenses or curved mirrors and other optical elements to make distant objects appear magnified. Telescopes come in different varieties such as the refracting telescope, reflector telescope, and the compound telescope.
How Much Does A Good Telescope Cost?
The cost of a good telescope depends on how much you want to spend. Telescopes range in price from $50 for a beginner model to over $4000 for large refracting and reflecting models. The type of telescope you choose depends on what you intend to use it for, where you intend to use it, the strength of the light pollution around the area, and how much space in your observatory you have.
Reflecting Telescope Cost
Reflectors are also known as parabolic mirrors. A parabolic mirror is a type of reflecting telescope that uses curved mirrors to bend light rays.
A large parabolic mirror is necessary for good images at the eyepiece. Most telescopes use fully automated tracking systems, which permit you to view the sky without moving the telescope manually. Most reflectors are equipped with motors on the backside of the tube that move the telescope’s mirror in order to keep objects centered in your eyepiece as you view them.
Reflecting telescopes have a number of inherent advantages over refractors. These include being able to view light sources from greater distances and being able to observe celestial objects with less light pollution.
How much does a good telescope cost? Usually around $200-$1000, depending on the type of telescope and accessories installed.
Refractor Telescope Cost
Reflector telescopes are also known as Cassegrain telescopes. They come in two basic types, the cold mirror/primary mirror type and the hot mirror/secondary mirror type.
A cold mirror/primary mirror type is where the primary mirror of a Cassegrain reflector telescope is kept at a temperature below the ambient temperature. The main disadvantage here is that as the primary mirror cools, it absorbs heat from nearby parts of the telescope, making them colder and requiring additional time for proper thermal balance.
A hot mirror/secondary mirror type has its secondary mirror mounted at a temperature closer to ambient. This allows for more rapid thermal equilibrium.
A good telescope is worth every penny to anyone who dedicates their time and effort into learning about the Universe. When you spend money on a good quality telescope, it will be a worthwhile investment in your future!
