Images On Bayer Process

stellina how to process the fits beginning deep,aug 04, 2020 stellina - how to process the fits - posted in beginning deep sky imaging the smart telescope stellina (by vaonis) is known for its ease of use and the way it produces automatic images in jpeg format, straight from the beast. however, it has more to offer. it can be used as an astrophotography station that collects raw images in fits format (from now on.processing raw images in matlab,this process is called demosaicing, and produces the m-by-n-by-3 array of rgb values at each pixel location we typically expect common cfa pattern is the bayer array, shown in figure2. there are twice as many pixels that represent green light in a bayer array image because the human eye is more sensitive to variation in shades.
