WebApr 19, 2024 · The image scale and the FWHM numbers are mathematically related. The "internal" measure for FWHM is always in pixels, since that's the actual camera data. You multiply that number by the image scale to get arc seconds. So if you have a FWHM of 3 pixels, an image scale of 0.4 would be 1.2 arc seconds (3 times 0.4). WebJan 10, 2014 · On the flip side, the difference in SNR between a 1.5" FWHM and a 5" FWHM could be huge, as with a 1.5" FWHM you are more likely closer to diffraction limited with many moderate to shorter focal lengths, meaning most of the energy is not being "blurred", whereas with a 5" star, there is a lot of blurring and redistribution of energy.
