Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
no atmosphere
Object that only shine with radio waves and not in the visible spectrum an object hidden by dust that block visible light.
The area of technology associated with telescopes is astronomy. Telescopes are used to observe and study celestial objects such as stars, planets, and galaxies in the night sky. They come in different types, including optical, radio, and space telescopes, each utilizing different technologies for observation.
A telescope is primarily associated with the area of optical technology, which involves the design and use of instruments for observing and manipulating light. It also relates to advancements in imaging technology, such as CCD sensors and digital imaging, enhancing the telescope's ability to capture detailed astronomical images. Additionally, telescopes utilize software technology for data analysis and visualization, aiding in the interpretation of astronomical phenomena.
which power of a telescope might be expressed as "0.5 seconds of arc"?
Please refer to the link below. This will take you to a web site that discusses this. Multiwavelength astronomy is dedicated to observing the various spectrums of radiation emitted. That is called its light gathering ability. The 'aperture size' determines the amount of light (radiation) a telescope gathers This site might help you obtain a more in depth answer imagine.gsfc.nasa.gov IT IS CALLED "LIGHT GRASP" in an optical telescope and "RF GAIN" in a radio-telescope.

Easiest to do would be a RADIO telescope. Get lots of chicken wire or fine mesh wire, If you have an old 6-foot satellite dish , the kind most people call "BUDs", Big Ugly Dish, then you can use this for the basic form. It would be at least theoretically possible to gather lots of clear glass bottles, and if you're a glass blower, it might be possible to make your own lens, or optical mirror. Telescope construction is a pretty well developed art, and there are lots of books on how to build your own telescope.
A reflecting telescope only needs one mirror, the primary mirror which will focus incoming light to a single point. A digital telescope might place the digital recording media directly in front of the reflecting telescope without any additional mirrors (although perhaps some lenses). For practical purposes though, most optical telescope will have a secondary mirror that will either focus light straight back through a hole in the primary telescope mirror, or to the side of the telescope. Some telescopes, especially the large ones in observatories will have several mirrors directing the light path to the observer or recording equipment.
