differences and similarities between optical and Radio Telescopes used for astronomical observation?
can anyone list some differences and similarities between these two Types Of Telescopes?
difficult question to answer simply! similar: The Optical And Radio Telescopes reflectors both the use of parabolic reflectors to focus the radiation and direct it to an observation area. TELYS radio can combine individual instruments. (See up VLA in New Mexico.) The subject has to be above the horizon must be respected. (Generally speaking. There are exceptions to radio wavelengths.) You can record results. In the technique of radio interferometry, which often have to. Hmmm, that's all. Difference: A lot of ways. Optically, it appears to the human eye, directly or by CCD (Charge Coupled Device). Radio, you have a very weak signal to be greatly amplified and separated from the background radiation and noise amplification by the team as well. This requires some sophisticated analog and digital processing of signals. Then you have computers to record and analyze the data. You pick up most of your information by looking at graphs of the data rather than direct observation. (Though can graphic visual data of an optical telescope and photometric and spectroscopic readings for analysis.) Resolution, or in short, the ability to discern details of the fine is much higher in an "optical scope as a radio version. Any professional astronomers want to give me a hand?
William Herschel made and sold many telescopes of this type. He used his own 7ft telescope (which would have been very similar to this one) with a 6.2 inch aperture magnifying images 227 times (depending on the eyepiece used), to make his second review of the heavens in 1781 from his house in New Kings Street, Bath. It was during this review that he discovered the planet Uranus. Herschel was able ...
This telescope is typical of the type used on board ship in the mid-19th century for general observations. It has a tapered leather-covered barrel and a single brass draw tube. The other brass fittings include a pivoted eyepiece cover and an objective lens cap. The makers name is inscribed on the draw tube as Troughton a Simms / London.....
This achromatic telescope is typical of the type used on board ship in the early 19th century. It has a leather-covered barrel and a single brass draw tube. The other brass fittings include a sliding eyepiece cover, although the objective lens cap is now missing. The makers name is inscribed on the draw tube as W. a T. Gilbert. / Mathematical Instrument Makers a Optns / to the Honble East India Co...

The Kendrick Dew Remover System is centered around the standard controller, which is required for activating the heater. (not included) The heaters have been built to use only as much power as necessary and thereby not waste energy. They have sponge insulation on one side to prevent heat being lost into the atmosphere. The heat is directed into the optics instead and because of this, less energy ...
