Build Simple Telescope Mailing Tubes. Telescoping tubes expand in length to accommodate different size documents with the same tube. Heavy-duty 1/8" double wall, spiral wound construction. Tubes have a 6". Cardboard telescoping mailing tube, with an inner and outer tube that telescopes. These can be found in most office supply stores: Diameter of 50 mm (about.
Building a telescope out of mailing tubes is an easy and inexpensive way to view the night sky. It is a great way to introduce children to astronomy, and is also a fun project for adults. With a few simple materials and tools, anyone can construct a basic telescope.
To begin, the materials needed for the telescope include two mailing tubes, one for the eyepiece and one for the objective. It is important to ensure that the tubes are of the same diameter, as this will make the assembly process easier. Additionally, some adhesive tape, a piece of glass, and glue are necessary. The tools needed are a hacksaw, a drill, a file, and a ruler.
The first step is to cut the tubes to the desired length. The length of the eyepiece tube should be equal to the diameter of the objective tube. To do this, measure the diameter of the objective tube and mark it on the eyepiece tube with a ruler. Then, use a hacksaw to cut the eyepiece tube to the desired length.
The next step is to drill holes in the tubes. On the eyepiece tube, drill two holes, one at either end. On the objective tube, drill one hole at the end. It is important to ensure that the holes are big enough for the screws to fit through.
Then, adhere the eyepiece tube to the objective tube with adhesive tape. This will ensure that the two tubes are securely attached. After this, it is time to cut the piece of glass for the objective. Measure the diameter of the objective tube and mark it on the piece of glass. Then, use a hacksaw to cut the glass to the desired size.
The final step is to attach the objective and eyepiece to the tubes. Place the piece of glass in the objective tube and secure it with glue. Then, attach the eyepiece to the eyepiece tube. Finally, use screws to attach the eyepiece tube to the objective tube.
Once all the components have been assembled, the telescope is ready to use. All that is left to do is to adjust the focus and start looking at the night sky. Building a telescope out of mailing tubes is an easy and inexpensive way to explore the wonders of the night sky.

This really Simple Telescope was designed by SASTA – the South African Agency for Science & Technology. The telescope’s tube consists of 3 cardboard tubes, each 30-cm long. There are two lenses – the BIG OBJECTIVE is Convex-concave and the SMALL EYEPIECE is Concave-concave. The three tubes of slightly different diameters fit into each other and can easily slide. Thus the length of the tube can be increased and decreased. The sliding of the…
To build a simple refracting telescope. Introduction A simple refracting telescope is very easy to create. All that is needed are two convex lenses and two cardboard tubes. The ﬁrst. The tubes and the mirror box are numbered 1 through 8 and the numbers are always aligned to each other (see image below). The crushed ends are also painted yellow (see image., Build Simple Telescope Mailing Tubes.
