Focal Length Extension Tubes Telescope. I was shocked by how many extension tubes I had to use to reach focus: a total length of 251.5 mm.! Adding the 66.5 mm. length of the focal extender and 103. We are now accepting pre-orders. Early bird pricing available for orders placed by June 30. Preliminary info provided by ZWO: Sensor:IMX462. Product Size:142*129*257mm.. A telescope extension tube is an additional, optional piece of equipment that can be added to a telescope. Its purpose is to increase the telescope’s focal.

Focal Length Extension Tubes are an invaluable tool for amateur and professional astronomers alike. They are designed to extend the focal length of a telescope, allowing the user to observe distant objects in greater detail. In this article, we will discuss how to use these tubes and the benefits they offer.

The first step in using focal length extension tubes is to attach them to the telescope. This is usually done by screwing the tube onto the telescope’s barrel or attaching it via a bayonet mount. Once attached, the tube will extend the telescope’s focal length, allowing the user to observe objects that are further away than before.

Once the tubes are attached, the user can then adjust the focus of the telescope to get the best possible view of their target. This is done by turning the focus knobs on the tube to adjust the position of the tube’s lenses. It is important to note that the position of the tube will affect the amount of light that is gathered, so it is important to make sure that the tube is properly adjusted.

Focal Length Extension Tubes also offer a number of other benefits. For example, they can be used to increase the magnification of the telescope, allowing the user to observe smaller objects in greater detail. Additionally, they can also be used to increase the brightness of the image, making it easier to observe faint objects. Finally, they can also be used to reduce the amount of light entering the telescope, reducing the amount of glare and making for better views.

In conclusion, Focal Length Extension Tubes are a great tool for amateur and professional astronomers alike. They offer a number of benefits, from increasing the magnification to reducing the amount of glare. With a bit of practice, anyone can learn how to use these tubes to get better views of distant objects.

As always, it is important to practice safety when working with any type of telescope or accessory. Be sure to follow the manufacturer’s instructions to ensure that the telescope is correctly assembled and that the focal length extension tube is properly attached and adjusted. With a bit of practice and patience, anyone can learn how to get the most out of their telescope with the help of focal length extension tubes.

In front of the focal plane, some telescopes need extension tubes in order to add length to the original telescope tube. This is particularly true if your scope is. The amount of reduction is simply the percentage by which a reducer shortens the effective focal length of a telescope and is calculated as (1 – Reduction., Focal Length Extension Tubes Telescope.


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.
