What are telescope mirrors, and how do they work?
- Reflecting Telescopes are a type of telescope that reflects light back to the observer. Reflecting telescopes focus light by refracting it via mirrors rather than lenses. A convex mirror is used to collect light and reflect it back to a focal point. It has a concave surface. Another mirror is used to guide the light from the telescope into the eyepiece in order to obtain the light out of the telescope.

What type of mirror should be used for a telescope?
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 can I make a reflecting telescope at home?
Make a Reflective Telescope out of cardboard.
- Lens from a tiny magnifying glass
- Concave mirror (with some magnification).
- A thick cardboard tube with a diameter equal to the focal length of the mirror. 2–3 cm in diameter
- two smaller tubes around 10 cm in length and 2–3 cm in diameter. a flat mirror measuring 2 cm by 2 cm
- Chopsticks or a thin wooden dowel (that is not rounded) with edges.
Can you use a makeup mirror for a telescope?
A telescope is constructed from Howell’s cosmetic mirror and her compact mirror. Make the major mirror box out of sticks, and the secondary mirror box out of sticks that will serve as trusses.
How thick should a telescope mirror be?
Telescope Mirrors That Are Too Thin Long ago, amateur astronomers and telescope manufacturers believed it was vital that the glass used in telescope main mirrors have at least a sixth the thickness of the mirror’s total circumference.
Why do reflecting telescopes not use Convex mirrors?
Reflecting telescopes focus light by refracting it via mirrors rather than lenses. In order to collect light and reflect it back to the source, a concave mirror is employed. Another mirror is used to guide the light from the telescope into the eyepiece in order to obtain the light out of the telescope.
Which of the following telescope contain convex mirror?
Telescope with a Cassegrain focal plane In this telescope, after being reflected by the concave mirror, the light rays are reflected back towards the concave mirror by a smaller convex mirror.
What can you see with an 8 inch reflector?
Quite a deal of the landscape will be visible to you! Open clusters and globular clusters will look fantastic, while the fainter globs will not appear to be very impressive. Because of your mild light pollution, some galaxies will not be seen, but many others will.
Can I use shaving mirror in telescope?
The premise of this article is that you have a concave shaving mirror that you wish to convert into a telescope. The short answer is that you can’t – or, more accurately, that you can create a telescope, but it will be so hazy that it will be completely ineffective.
Do telescope mirrors warp?
FABRICATION OF THIN MIRRORS FOR TELESCOPES THAT REFLECT Written by HAROLD C. The result will be warping due to the fact that “it will bend with its own weight,” as the phrase goes in the industry. The notion that thin mirrors warp as a result of their own weight is irrational on its face, even if it is true that thin mirrors are discovered to warp.
How long does it take to grind a telescope mirror?
It probably took me 80-100 hours to simply grind the telescope mirror, but I was learning a lot and taking my time with the process.
