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:

WebThe Airy Disk. When light passes through any size aperture (every lens has a finite aperture), diffraction occurs. The resulting diffraction pattern, a bright region in the center, together with a series of concentric rings of decreasing intensity around it, is called the Airy disk (see Figure 1).The diameter of this pattern is related to the wavelength (λ) of the illuminating … WebIn the most fundamental sense both bandpass and resolution are used as characterization of an instrument's ability to separate adjacent spectral lines. Assuming a continuum light source, the bandpass (BP) of an instrument is the spectral interval that may be isolated. This depends on many factors including the width of the grating, system ...
