. This composite of false-color infrared images from Cassini reveals the exotic surface of Titan's southern hemisphere. Yellow areas correspond to regions rich in hydrocarbons, while green represents areas with an abundance of ice. A methane cloud at Titan's south pole, which is bright in all three wavelengths, looks white. The circular feature visible at top right may be an impact crater. NASA / JPL / ASU

... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...
