How to choose a telescope
Step by step reading
A) to understand the basics of astronomical telescopes
Telescope-refraction, reflection and catadioptric 3 species:
1. refraction type is more convenient to use, view larger, Star bright, chromatic aberration, resulting in lower resolutions. Quality refractor objective lens is two pieces separated double achromatic objective lens or 3 apochromatic lenses. However, achromatic and apochromatic and fail to eliminate chromatic aberration.
2. mirror has the advantage of no chromatic aberration, however, mirror the coma and astigmatism is large, makes the edge of vision as a qualitative difference. Mirrors are commonly used both Newtonian and Cassegrain. The former simple optical system, cheap, spherical mirror on the back end, in front of the eyepiece side; Optical system of the latter master, parable that mirror aspherical, and eyepiece are behind the primary mirror, image quality is good, the price is more expensive.
3. fold mirrors the advantage of both the refractor and reflector: vision, good image quality, lens barrel shorter, easy to carry. Compared with the refractor of focal length and the same caliber, price is less than one-third. Folding mirror Schmidt-Cassegrain and Maksutov-Cassegrain type two kinds, the latter also known as Ma-mirror card. Horses-mirrors are available in both two and three plates. For example: Bosma, BOSMA1800150 and BOSMA2400200 are three piece, due to image quality is better than two pieces, popular astronomer welcomed at home and abroad.
