Which optical effect compromises telescope resolution at high magnifications?

A)Atmospheric seeing causes scintillation artifacts
B)Chromatic aberration blurs color fringes
C)Spherical aberration distorts point sources
D)Vignetting produces brightness falloff

💡 Explanation

Atmospheric turbulence alters the refractive index randomly, therefore causing constructive and destructive interference called atmospheric seeing, because light path lengths vary randomly, rather than forming a perfect image as limited by lens quality alone.
