Caption for new AAO colour picture of Comet Hyakutake . Comet Hyakutake was discovered by a Japanese amateur astronomer on 30 January, 1996, and it was soon realised that its orbit would bring it within 15 million kilometers of the earth, about one-tenth the earth-sun distance. It would therefore be the closest bright comet for 450 years. ...

... However to my eye the colour scheme that looks best is what might be described as a `thermal' one, ie one in which cool objects (objects with a long-wavelength excess) are coloured red and hot objects blue, with the intermediate sequence going from red through yellow and white to blue. ... The parameter heat shifts colours along the thermal sequence: at heat = -1 all colours go to red, at +1 they are all blue, with again 0 having no effect. ...

Next: XWindow display Up: IP8500 display Previous: Alphanumerics . The IP8500 allows pictures to be displayed in true colour using three image memories (channel 0, 1 and 2) simultaneously for the red, green and blue images needed to make up a true colour image. Channel 0, 1 and 2 may also be referred to as Red, Green and Blue. To start using the RGB mode of the display, execute the command: SET/DISPLAY RGB . ... Next, each channel must be loaded individually with the appropriate image. ...
