A wile ago I came across Damian Peach's animated Pickering scale for determining the seeing conditions through a telescope by looking at the diffraction pattern of a star. You need high magnification to see the diffraction pattern of the star (the Airy disk).

I got Damian's written permission to make these charts available.

Attached to this post you'll find a chart version (PDF, 1 page, landscape).

I also produced a 2-page version with slightly larger images (PDF, 2 pages, portrait), which I attached to this post.
