Dawes Limit Max. Resolving Power of a
Scope Resolving Power Spatial Resolution ability of Scope to distinguish Points affected by - Aberration Shape & Quality of Optics Diffraction - Wave Nature of Light determined by Aperture Creates Airy Pattern - Ring Diffraction Pattern 2 points are Resolved if Principal Diffraction of pt.1 is grater distance from Minimal Diffraction of pt. 2 Metric Dawes Limit Centimeter Aperture divided by 11.6 = Arcseconds American Dawes Limit Inches Aperture divided by 4.56 = Arcseconds Link - Calculate Dawes Limit |
