Telescope extension tubes are an important part of a telescope system. They are used to increase the focal length of a telescope, thus allowing for higher magnification. Extension tubes come in many sizes, from small, medium, and large, depending on the telescope’s size and the desired magnification. Extension tubes are also used to connect two telescopes together to form a binocular system.

The purpose of an extension tube is to increase the focal length of a given telescope. This is done by positioning the telescope’s primary lens further away from the eyepiece. As a result, the telescope’s eyepiece will be able to magnify objects more closely than it could before. Extension tubes are also used to couple two telescopes together to form a binocular system. This is a great way to view distant objects in greater detail.

When selecting an extension tube, it is important to consider the telescope’s size, focal length, and the desired magnification. The size of the extension tube should match the telescope’s size and the desired magnification should be within the telescope’s capabilities. For example, a small telescope with a focal length of 400mm would require a medium-sized extension tube to achieve a magnification of 1000X.

When using an extension tube, it is important to make sure it is securely mounted to the telescope. Extension tubes are usually mounted with screws or clamps and should be tightened to ensure a secure connection. Once the extension tube is secured, it should be aligned with the telescope’s eyepiece. This is done by adjusting the focuser until the image is clear.

Having received helpful feedback from forums and friends over the years, I felt it was time to give back to the online community to assist with making decisions when it comes to metal tubes. Furthermore, it is going to eliminate you from losing valuable time and cash - it’s the real reason I created this site - to help others make a promising choice.
