"WebWe describe the sharpness of the stellar images by their Full Width at Half Maximum, or FWHM for short. In this particular instance, the FWHM was about 1.67 pixels, or about 3.7 arcseconds (since the RIT 10-inch telescope with CCD yields a scale of about 2.2 arcsec per pixel). You can see the FWHM if you zoom in and change the contrast: " - How does fwhm affect resolution
