The New Amateur Astronomer
Thus, from the formula above, the focal length required to achieve 1 arc-second/
pixel is 206 x 9/ 1 - 1854 mm (73 inches) and for 2 arc-second/pixel, 927 mm (
36.5 inches) is required. The field of view at 1 arc-second/pixel will be 765 ...

The Observer's Guide to Astronomy:
Using this method, seeing may be estimated as 0.25 arc-second when the
diffraction rings are seen to be continuous in a 140-mm telescope. (Under the
same conditions, the rings appear broken in a 280-mm telescope; the image is
greatly ...
