Have a quick question on telescope mirrors.

I know plate glass is not the best thing to make telescope mirrors, however this aside, if one were to grind a larger size mirror from plate glass, but rather than use a thick blank, cut several thinner blanks and laminate them together to get a thickness.

Would this cause major problems?

A telescope is an optical telescope that uses a unique combination or curved mirrors that reflect light to form an image. Since telescopes use mirrors the thought that behave like mirrors curved lenses back to Alhazen 11 century treaty on optics, the work that had been widely disseminated in a Latin translation in modern Europe. The potential benefits of the use of parabolic mirrors, mainly the reduction of spherical aberration, chromatic aberration-free. silvered glass mirrors in the 19 century, aluminum siding long term in the 20th century. Segmented mirrors that allow a larger diameter and active optics to compensate for the gravitational distortion. In mid-20th century innovation was catadioptric telescopes such as Schmidt camera, which uses both a goal and the mirror as the main optical elements are used primarily for imaging large field without spherical aberration.

It took ages for me to get my gamertag linked, because EA site bugged for me. I finally got it to work not so long ago, and am finally able to see screenshots I've taken. And those were taken by accident, when I didn't know how to take 'em (only noticed the feature when "achievement unlocked" popped on my screen, for unlocking the one that you get from taking 3 screenshots). So they are mostly just closeups of ground, with couple knifekills
