Use Cork In A Newtonian Telescope Tube. This will enable you to use both 1.25” and 2” eyepieces, and some come with both a coarse and fine focus. If you’re doing astrophotography, you might find that your. Ideal minimum height of focuser from tube would be 58mm or smaller and the focuser draw tube wouldnt stick out more than 20mm from the id of the tube – too.
Cork is a widely used material in the construction of a Newtonian telescope tube. It is an ideal material because of its properties of light weight, strength, durability, and low cost. In this article, I will explain how to use cork in a Newtonian telescope tube.

The first step is to measure the length of the telescope tube. This will determine the size of the cork you will need. You can use a ruler to measure the length and width of the tube, or you can use a tape measure. Make sure to measure the outside diameter of the telescope tube.
Once you have the measurements, you can cut the cork to size. Make sure to use a sharp knife or scissors to avoid any potential damage. You may also need to sand the edges of the cork to make sure the pieces fit snugly. If the cork is too thick, you can use a sanding block to thin it out.
Once the cork is cut to the desired size, you will need to apply adhesive to the telescope tube. You can use epoxy glue, or you can use a hot glue gun. Make sure to follow all the instructions on the glue package, as different glues may require different methods of application.
Once the adhesive is applied, you can place the cork onto the telescope tube. Make sure to press the cork firmly against the tube to ensure a good seal. Once the cork is applied, you can use a hammer to tap it into place. Make sure to tap gently, as excessive force may damage the cork.
Once the cork is in place, you can use a drill to make any necessary holes in the cork. These holes are necessary for mounting the optics and other components onto the telescope tube. Make sure to use the appropriate drill bit size for the holes you need.
Finally, you can use a screwdriver to secure the cork to the telescope tube. Make sure to use the appropriate screws for the type of telescope tube you are using. Once the screws are in place, you can use a wrench to tighten them. This will ensure that the cork is securely in place.
