Abstract

A solar focus and seeing monitor is described which utilizes the properties of an image of the telescope objective formed after putting a knife edge next to the solar limb. In a very simple way simultaneous measurements are obtained for the telescope focus and for the image motion and blurring produced by the earth’s atmosphere.
