Length Of Telescope Tube. Our 8 inch (nominal), 4 foot (actual) concrete form telescope tube, purchased at a national chain home center. The actual tube inside diameter is 8 inches, with a 1/8 tube thickness. If you see a telescope that has a focal length of 600mm (roughly 24”) and automatically assume that will be the length of the tube only to find out that the tube is actually 30”.
Telescope tube length is an important consideration when it comes to choosing the right telescope for your needs. Telescopes come in a variety of lengths, and the length of the tube can affect the quality of the images you get from the telescope. In this article, we’ll discuss how the length of the telescope tube affects astronomical viewing.
The length of the telescope tube is related to the amount of light that enters the telescope. A longer telescope tube will allow more light to enter, which in turn will give you brighter and clearer images. The longer the tube is, the more light will be collected, resulting in better images. However, a longer telescope tube can also be more difficult to handle, as it is heavier and more awkward to transport.
The length of the telescope tube also affects the field of view. A longer tube will have a wider field of view, allowing you to see more of the sky at once. The field of view is an important consideration for those who are interested in taking wide-field images of star clusters and galaxies.
When selecting a telescope, it is important to consider the size of the tube and the type of mount. A larger tube will require a more substantial mount, such as a tripod, to support its weight. The larger the tube, the more substantial the mount needs to be. A smaller tube can be mounted on a smaller mount, but it may not be able to collect as much light.
One way to determine the right telescope tube length for you is to consider the type of objects you are interested in viewing. If you are interested in viewing faint objects such as galaxies and nebulae, a longer telescope tube will be necessary. If you are interested in viewing bright objects such as planets and the moon, a shorter tube may be sufficient.
Another way to determine the optimal telescope tube length is to consider the size of your observing site. A larger observing site will require a longer telescope tube in order to take advantage of the extra space. If your observing site is smaller, a shorter telescope tube may be sufficient.
Finally, the type of telescope you choose may also determine the optimal telescope tube length. Refractor telescopes are generally shorter than reflector telescopes, so if you are interested in a refractor telescope, you may not need a longer tube. On the other hand, a reflector telescope will typically require a longer tube to take advantage of its larger aperture.
In summary, the length of the telescope tube is an important factor to consider when choosing the right telescope for your needs. A longer tube will allow more light to enter, resulting in brighter and clearer images. It will also have a wider field of view, allowing you to see more of the sky at once. The type of telescope you choose, the size of your observing site, and the type of objects you are interested in viewing will all help determine the optimal telescope tube length for your needs.
