... The removal of the bright sky background from your IR images is one of the key steps in the data reduction process. Once bad pixels have been removed from all the astronomical frames, the object frames must have the matching sky background images subtracted from them. ... The simplest sky subtraction is where you have separate sky and object frames taken a short time apart. ... The resulting sky subtracted images should be examined to make sure that sky subtraction has been properly achieved. ...
