In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... The WFPC2 cameras have significant geometric distortion which not only affects astrometry, but also affects photometry (because the extended sources used to generate flat fields have an induced change in apparent surface brightness). It can be a large effect, with "true" positions differing from observed positions by several pixels in the corners of the cameras. ... The cubic distortion coefficients can be used to derive effective pixel areas as presented in Figure 5.12 . ...

... The Large Magellanic Cloud is a Dwarf Irregular galaxy in orbit around our own Milky Way. It is a large object, several degrees in size, and easily visible to the unaided eye in Southern Hemisphere skies. The LMC is located in the constellation of Doradus at about 5h30m Right Ascension, -68 degrees Declination, and lies at a distance of roughly 50 kiloparsecs (160,000 light years) from Earth. ...
