... Almost all DSOs require a telescope to see in any detail at all, though some can be detected with just binoculars, and a few can be barely seen with the unaided eye. ... DEGREE: Distances on the sky (sometimes called the celestial sphere) are measured in angular degrees rather than inches or feet. ... The magnification is the focal length of the telescope divided by the focal length of the eyepiece. ... Short focal length eyepieces are also termed high power, long focal length are low power. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...

... ARC 3.5m | ... 2.1 Choosing and Exposure Time . 2.2 Choosing the CCD Gain . ... 3.2 Read Times and Read Noise . ... At the slow read rate of 100 KHz to be used for exposure times longer than a few seconds, we determine an average read noise of order 3.7 ? ... Table 2: Exposure time must be greater than the readout time by at least 0.03 s. The Agile CCD camera has two readout amplifiers, one of which is capable of reading at the fast readrate of 1MHz while introducing a read noise of order 7 ? ...

P.O. Box 797 Sonoita, AZ 85637-0797 June 19, 2000 Prof. David Chalmers Philosophy Department Room 213, Social Sciences Building University of Arizona Tucson, AZ 85721-0027 Dear Prof. Chalmers: Well, here's another one from Mr. At-Least-I-Thought-Of-It-Independently. ... So as a thought experiment, let's imagine that instead of having our matter transporter actually move matter, what it moves is information. ... That will make it necessary to move the matter to move consciousness. ...

... Meade Instruments Corporation . ... Meade Pictor XT-Series CCD Autoguider/Imagers . ... Properly set up your telescope as described in your telescope user's manual. ... Focus the telescope for use with the camera. Focusing a telescope with a CCD camera attached is one of the most difficult tasks in CCD imaging. ... This is so that a part of the image (the part you want to focus on) is downloaded each time, for quicker response. ... Copyright 2006 Meade Instruments Corporation, All Rights Reserved. ...
