WebJul 2, 2013 · Indeed, most of our image look best through longer wavelengths (red or near-infrared). However, we are also teached by the laws of optic that in theory, the resolving power of a telescope is, on the contrary, better in the short wavelengths (blue light). It is easy to verify this by experimentation.
