WebIn astrophotography (and many other fields of signal processing) there is an important term called the sampling rate. A sampling rate is simply how many times you measure a signal over some dimension. For example, let's say you’re a gold miner who has a plot of land with an area of one square mile. WebThis useful and easy-to-use freeware tool simplifies the pre-processing steps of creating a beautiful deep sky image. The concept of image stacking in astrophotography is simple, by combining multiple images together, the signal-to-noise ratio can improve.
