What is the most efficient method of grinding mirrors?

  • Roughness in stroke numbers, tool rotation, and disc rotation are all important factors in good mirror grinding. Making a tile tool out of tiles that have been broken with a hammer can help to increase the unpredictability of the game:) Always work with water on your hands!

How do you find the center of a telescope mirror?

Make a small hole there, about 1/10-inch in diameter. Another option is to measure the diameter of your mirror and draw a circle on a blank sheet of paper using a compass (with the needle set to 12 times the mirror’s diameter). The center of the circle will be defined by the pinprick of the compass point on the paper.

What type of telescope is a Dobsonian?

A Dobsonian telescope (which utilizes a mirror rather than a lens) is similar in design to a Newtonian telescope in that it is a reflecting telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).

What are the different telescope eyepieces?

What are the many types of eyepieces available?

  • Plössl’s optical instrument. Plössls have a large field of vision (about 52°), which allows them to be used successfully for both planetary and deep-sky gazing. The radian eyepiece is a kind of telescope. The Radian eyepiece is one of the more recent types of eyepieces to hit the market. Barlow lens
  • Nagler eyepiece
  • Orthoscope eyepiece

What type of mirror is used in telescopes?
