... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

... The recently discovered quasar labeled APM 08279+5255 has set a new record as being the brightest continuously emitting object yet known. APM 08279+5255 's great distance, though, makes it only appear as bright as magnitude 15.2, an object which can be seen with a moderate sized telescope. ... One possible explanation of APM 08279+5255's record luminosity is that it is partly a mirage: its light is highly magnified by an intervening galaxy that acts as a gravitational lens . ...

TUI supports the following offsets: . Object Arc offset by a given amount on the sky (i.e. along the arc of a great circle). ... Arc offsets are useful for moving a different portion of your object or a different nearby object onto the boresight . ... Object Arc XY this is identical to an Object offset except that it has been rotated to align along the instrument x-y axes. ... This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...

Turning the Camera Skyward . A reconfigured camera can take wide-field exposures of astronomical objects (constellations, the Milky Way, zodiacal light, moving artificial satellites, meteor showers, variable stars, etc.) to reveal much fainter objects and structures than seen by naked eye. ... This picture reveals objects more than 2.5 times fainter than can be seen by the naked eye, including not only stars but also the Orion nebula (M42), where new stars are being born. ...

... Why does X-ray astronomy require satellite telescopes? ... That is why scientists use space based satellites to record and observe data from X-ray sources. ... It primarily observes X-ray sources and has a moderate imaging capabilities. ... X-rays (because of their short wavelengths) , as opposed to visual light, can penetrate through otherwise opaque objects e.g. bones X-rays can observe celestial objects that emit shorter wavelengths such as galaxies , quasars, and black holes. ...

... Meade Instruments Corporation . ... How to Calculate Power . How to Calculate Power: The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed. ... Example: The Meade DS-2070AT telescope has an objective lens focal length of 700mm; when this telescope is used with a 25mm eyepiece, a power of 700/25 = 28 power (written as "28x") results. ... about meade | ...
