Values for other filters or sky brightnesses can be computed from Table 6.2 , Table 6.1 , Table 6.3 , and Equation 6.2. Table 6.4: Sky Count Rate per Pixel (P sky ). ...

... One of the major activities going on at my Mira observatory at Sava, Italy, is to record deep sky CCD images for a personal atlas I'm currently working on. ... Images are made using a SpectraSource CCD HPC 1 camera equipped with a Texas Instrument TC215 chip, 1024 square, 12 micron pixels size, at 16 bit. ... After a 40sec exposure, the PC monitor showed a faint glow just above the camera termal noise. ... The image showed clearly a star in the galaxy core, of magnitude 14.5, some 50sec. ...

... Colours of stars and galaxies hold information on intrinsic and extrinsic parameters, such as stellar temperatures and galaxy populations, selective absorption and colour changes due different dust contents and inclination angles of galaxies, as well as galaxy redshifts and evolution. ... The colour magnitude diagram of 65000 galaxies to which all above-mentioned quantities and others contribute can only be explained by comparison with simulations. ... Colours are also of technical help. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
