The Pickering seeing scale

When logging your deep sky observations, try to log the seeing, transparency and sky darkness of the night of observing. For the seeing you can use the Pickering seeing scale.  The scale is based on what a bright star looks like in a small telescope, using high magnification. It is a 1 to 10 scale, where 1 is very poor and 10 is excellent / perfect. As the scale is made using a 5-inch reflector, the results for other telescopes could be different. You probably have to modify the Pickering scale for your personal use. Visit Damien Peach’s website where you can find an animated version of the Pickering’s seeing scale. This will give you a very good idea of the different types of seeing you can expect.
