what is a small telescope called

EYEPIECE A small microscope fitted to the telescope to magnify the image formed by the main optic. Even sophisticated designs, such as the Ritchey–Chrétien and (corrected)[clarification needed] Dall–Kirkham, which have traditionally been the preserve of large professional-grade instruments, have become available to amateurs. The range of amateur astronomers' telescopes is wide, with numerous types and designs. A refracting telescope has a large lens at the front which collects and focuses the light, and you look at that image through a smaller lens called an eyepiece. As Sky & Telescope explains, there are a number of distinct types, but they all fall into three broad categories: refractors, reflectors, and compound telescopes (also called catadioptric). The telescopes that we've just looked at are all visible light telescopes also called optical telescopes. - Lesson for Kids: Definition & Facts, CSET Science Subtest II Earth and Space Sciences (219): Test Prep & Study Guide, Shiloh by Phyllis Reynolds Naylor Study Guide, Introduction to Natural Sciences: Certificate Program, UExcel Weather and Climate: Study Guide & Test Prep, Holt McDougal Earth Science: Online Textbook Help, Middle School Earth Science: Help and Review, 6th Grade Earth Science: Enrichment Program, Natural Sciences for Teachers: Professional Development, Astronomy 101 Syllabus Resource & Lesson Plans, Ohio Assessments for Educators - Earth & Space Science (014): Practice & Study Guide, Holt Science Spectrum - Physical Science with Earth and Space Science: Online Textbook Help, Holt McDougal Introduction to Geography: Online Textbook Help, Praxis Geography (5921): Practice & Study Guide, Biological and Biomedical Nancy.

It is designed for two classes of missions: one for small telescopes, the other for very large telescopes. Because of their limited light-gathering capability, small telescopes are usually not well-suited to spectroscopy, although some useful spectroscopic work can be performed with reflecting telescopes with a primary mirror as small as 14 inches (360 mm) when equipped with the increasingly sophisticated CCD imaging and spectroscopic instrumentation that has become available to amateur astronomers in the 21st century.

The human eye is very small relative to even the smallest of telescopes. As mentioned in a previous article, the most important specification of any telescope is the aperture, the diameter of the main lens or mirror of the telescope.
