... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...
