There are telescopes of several brands that are freely available in the market. However, even for one who wants to construct his telescope at home, there are several viable options.
One way to go about constructing a telescope is to buy each individual component and then assemble the whole structure. The required elements are mirrors, concave and convex lenses, the housing structure, brackets, and some other components. These can all be bought at local shops or in online stores. A comprehensive list of required elements can be downloaded from websites that serve as guides for amateurs looking to build their own telescopes. Books dedicated to this subject are available.
An enthusiast may also want to construct each element by hand at home, though that is an extremely time-consuming process and not the usual home method. It is a cumbersome process to create the housing compartment and arranging each element inside it. If one wants to follow this method, then one must be prepared to face several hurdles in the construction process.
Another method is to make use of telescope kits, which are available in the markets. These kits contain all the required elements and include instruction manuals to guide amateurs working at home. Using kit elements and assembling the instrument is considered a better method than constructing a telescope from individual elements bought separately. Telescope kits are cheaper and far less time-consuming than other methods of telescope construction. They save time spent on searching for each required component. Step-by-step instructions make it possible to work faster, making fewer mistakes along the way. These kits are intended for amateurs, and first-timers not yet experienced in making telescopes. A professional astronomer or one who aims to become a professional may however choose to work from scratch.
The point of consideration now is whether homemade telescopes are better than readymade instruments available otherwise. The simple answer to such a question is that both are almost the same with respect to quality. A homemade instrument displays the same characteristics as a readymade one of the same specification. A telescope made at home will have the same magnification factor, and is simpler to use in comparison to one bought in a shop. In fact, it is not complex at all and is similar to the ones built by early astronomers like Galileo.
The construction of telescopes at home, in truth, is often a joy, and a hobby that many enjoy. Several people consider it akin to an art, and have dedicated themselves to creating perfect instruments at home. Several sites online are a medium for proud astronomers to display their homemade telescopes. There are also web pages in existence that are dedicated guides for amateurs who want to create their own telescopes. Such pages give comprehensive lists of the elements required for its construction as well.
As with any other task, exhaustive research is required before setting out to make a telescope. It is imperative that the builder understands how each element performs individually and how it affects the whole. It also advisable to have storage space for the material required in construction of a telescope. However, despite all the effort that goes into construction of a homemade instrument, the results are reward enough.
