Oct 03, 2016· The world's largest optical telescope mirror has been constructed at the Canary Islands. Built by Spain, it has a mirror of m diameter. In contrast, the Hubble space telescope has an aperture of only meter. Nowadays, large mirrors in telescopes are also segmented in order to overcome the problem of sagging under their own weight.
Sep 26, 2017· Researchers are developing new protective coatings for large silverbased telescope mirrors by adapting a technique widely used in the microelectronics industry. According to Phillips, most astronomical telescope mirrors use aluminum for the reflective layer, despite the superior reflective properties of silver.
Aug 28, 2015· The mirror box encloses the mirror cell and allows the entire telescope to rotate vertically. I built mine entirely from CNCcut ¾" plywood, and fastened it together with 2½" bolts. It features 2 semicircular arms, and mounting points for the trusses (Tnuts are fine), as well as a lid to keep the mirror safe when the telescope is not in use.

The reflector telescope uses a mirror to gather and focus light. All celestial objects (including those in our solar system) are so far away that all of the light rays coming from them reach the Earth as parallel rays. Because the light rays are parallel to each other, the reflector telescope's mirror has a .
Each optical surface is tested up to 29 times as it passes through its many processes of being turned from a blank piece of glass to a highly accurate figured mirror or lens. Below is our selection of Telescope Mirrors available to purchase and a brief description of each grade's qualities.

Now that I have several blanks made, it is time to grind and polish one into a telescope mirror and test it out. I can use one blank as the mirror and another as the grinding tool, and have a couple in reserve in case something goes horribly wrong during the grinding and polishing operations. I'll post an update once a mirror is completed.
Optical tube: This is the body of the telescope that holds the lenses and mirrors inside of it. Software: Many telescopes, even beginner models, ship with software to help aim the telescope. If you seek more features, you could also purchase software separate from what accompanies the telescope.

We had communicated for year on the net. I had my 16 F5 telescope whose mirror I made and knew very well from the interferometry data. The telescope itself was still a work in progress and I think the mirror was not yet coated. The telescope had no tracking and was very unstable. It jiggled when you toughed the eyepiece.
