WebSep 7, 2024 · For astrophotography, what people usually mean by sampling is sampling the FWHM of the Airy Disk -- FWHM about 60% of Airy Disk -- with a certain number of pixels. I say sampling the FWHM with 2 pix effectively gets you sufficient resolution -- others say 3 pixels. But if you are 4 or 5 pixels, then you can bin / downsample. WebJul 18, 2011 · FWHM is the width of the bell at its midway point hence "half". For all practical purposes you want this number as small as possible.
