How do you do the telescope?

The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.

radio telescopes are telescopes that detect radio waves. they also have ti be much larger then optical telescopes because radio wavelengths are about 1,000,000times longer than optical wavelengths....

Due to the larger weight involved with a larger telescope, a lens in a large refracting telescope will become distorted and no longer project an image to the proper focal point. With a reflecting...

The Hale Telescope is a 200 inch (5.1m) reflecting telescope with a focal ratio of 3.3. It is mounted on a "horseshoe" equatorial mount.

There are many orbiting telescopes, the hubble telescope is the best known. Most are for wavelengths absorbed by the air.
