How do you make a reflecting telescope?

How do you make a reflecting telescope?

Make a Reflective Telescope

1. Concave mirror (with some magnification)
2. Lens from a small magnifying glass.
3. Thick cardboard tube, equal to the focal length of the mirror.
4. Two smaller tubes approximately 10 cm long and 2–3 cm in diameter.
5. 2 cm × 2 cm flat mirror.
6. Thin wooden dowel (not rounded) or chopstick with edges.

How do you make a high power telescope?

Things You’ll Need

1. Cardboard telescoping mailing tube with a diameter of 50 mm and a length of 1,100 mm.
2. Concave-convex lens (the objective lens) with a diameter of 49 mm and a focal length of 1,350 mm.
3. Plano-concave lens (the eyepiece) with a diameter of 49 mm and a focal length of 152 mm.
4. Coping saw.
5. Box cutter.

What can you see with an 8 inch reflector?

You will be able to see quite a bit! Open clusters and globular clusters will be great, although the fainter globs won’t look like much. Some galaxies won’t be visible due to your moderate light pollution but many will.

What is the focal length of a reflecting telescope?

Focal length is the large number you’ll often see printed or engraved on the front or back of the scope, usually between about 400 and 3,000 millimeters. The focal length is often found on the front or back of the telescope. For this 135 mm (5.3-inch) Galileo telescope, it is 1,100 mm.

Can you make a telescope with a concave lens and convex lens?

A telescope can also be made with a concave mirror as its first element or objective, since a concave mirror acts like a convex lens as seen in Figure 3.

How do you build a refracting telescope at home?

Glue the lenses to the center of the frame. The shorter focal length lens will be the eyepiece. Glue that framed lens to the end of the smaller tube. Glue the other framed lens to the end of the larger tube. 3. Slide the two cardboard tubes together. You have now assembled a simple refracting telescope.

How to build your own sharp vision telescope?

You will have to build the following parts of the telescope yourself: 1 Main tube of the telescope 2 Mount for the main mirror* 3 Mount for the diagonal mirror* 4 Eyepiece focusing arrangement* 5 Finder telescope tubes 6 Finder telescope mount 7 Tripod stand 8 Dust covers for the tube

Is it possible to build your own telescope?

I found out pretty quickly that building my own telescope would only be a bargain if I made my own mirror and mechanical parts. This might have been tempting if I wanted to build a 6 inch scope—at that size, they say that first-timers do pretty well at grinding and figuring their own optics.

How big of a telescope do you need?

It is advisable to build a telescope not less than 5” (125mm) mirror diameter so that fittings inside the tube can be done without the use of special tools.
