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! Prior to beginning to grind, sprinkle some water on the grit.

How do you grind glass for a telescope?
The most common question I receive is, “How do you construct a telescope mirror?” My typical response is, “You take two rings of glass and rub them together for a long period with fine-grained sandpaper in between.” That’s exactly what you’ll be doing. For a short period of time. Increasingly deepens the curve in the mirror while the tool is on top (often abbreviated TOT).
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 is pitch lap?
In this spot, drill a hole 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’s point.
How do you polish a mirror on a telescope?
Place the mirror face-up on a towel and, with the drain open, spray the mirror’s surface with room-temperature water for a few minutes to remove any lingering residue. The majority of dust and grit will be securely removed in this manner. For removing grit from a telescope mirror, the most safest method is to blast the surface with tap water, as seen from left to right.
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?
The Primary Objective of the Reflecting Telescope or Reflector is a concave mirror, rather than a lens or lenses, which is used to focus the light entering the telescope. The kind of reflector is determined by the other system mirror(s), which are referred to as the Secondary Mirror.
How long does it take to make a telescope mirror?
Even inexperienced amateurs may construct good, sturdy, and useful telescopes. This is not true! A 6″ or 8″ mirror should take between 40 and 80 hours of work to complete.
