Refractor Vs Reflector Telescopes- There are generally two types of telescopes; reflector telescopes and refractors telescopes. The main difference between them is that the reflector telescope uses a mirror and the refractor telescope uses a lens for gathering and focusing the light. ...
Compound or catadioptric telescopes are hybrid telescopes that have a mix of refractor and reflector elements in their design. The first compound telescope was made by German astronomer Bernhard Schmidt in 1930. The Schmidt telescope had a primary mirror at the back of the telescope, and a glass...

I have couple of these and they actually work pretty well. If I remember correctly the eyepiece section at the top should move in and out when you turn the ring with the silver strips. There is a dot on the side that will line up with the numbers as you turn it to show you the f...
How do optical telescopes work? What is an optical fiber and how does it work? How do you calculate the actual mechanical advantage of a lever? How does vision work? What is the device that you use that uses the most sophisticated geometric optics? Describe how it works. ...
Why do mirrors seem to reverse things left-to-right but not top-to-bottom? Photo: Does a mirror really reverse things left to right? Try this cunning experiment yourself to prove that they don't! We learn in books that plane (flat) mirrors "laterally invert things" (flip them from ...
How do SETI telescopes work? How does a Telrad finderscope work? What are space telescopes and how do they work? How does an optical telescope capture information? How is the Hubble Telescope powered? How is the Hubble Telescope also a satellite? How does a liquid mirror telescope work? How...
If you want to make a phone call from the North Pole, you can fire a signal into space and back down again, using a communications satellite as a mirror to bounce the signal back to Earth and its destination. If you want to survey crops or ocean temperatures, you could do it from a...
All telescopes can utlilize either an alt-azimuth or equatorial mount with a tripod, but there’s a third type of mount that can only be used with a reflector. If your scope doesn’t have a tripod, it’s almost certainly a reflector on a Dobsonian base. This alt-azimuth mount looks ...
The one part of the telescopes I have never made for myself is the mirror blank. I know a guy who built a large trepanning saw and cut mirror blanks out of thick scrap glass. The machine was huge, took forever to cut the glass, and finding thick enough glass was very difficult. I ...
