Telescopes can both extremely complex and fairly simple. This gives birth to a wide range of telescope parts that are involved with the complete construction of one. Whether you’re one of those die-hard do-it-yourself type hobbyists looking to build your own, simply need a part to fix a broken piece on your telescope or are a telescope supply store looking to expand the accessories you carry, here are a few fundamental telescope parts that you simply can’t do without.
One of the leading parts involved in a telescope is a focuser. This is one of the parts on a telescope that is more easily discernible, and ever telescope has a focuser. They come in all different styles, but the function remains virtually the same from style to style. The focuser is the part that is attached to the tube of the telescope on the outside surface. This part holds the telescope eyepiece and is allows for several different movements (angle capabilities depend on the type of focuser) to help you achieve accurate focusing.
Then there is the telescope tube. You simply can’t have a telescope without a tube. Otherwise, it would as good as looking through a magnifying glass. This tube is also sometimes referred to as the optical tube. Although the materials can vary from tube to tube, they are essentially a hollow tube. Different styles of telescopes will have tubes that allow for varying setups and attachments to achieve different viewing capabilities.
One of the other more important parts is a primary mirror cell, holding the principle mirror and allowing for adjustments.
Among the more fundamental telescope accessories are mounts and eyepieces.
A space telescope lets us see objects that we would never be able to see from earth.
