I'll try for a response to this: There was an urban myth, popular in the years 1990-1994, that the ability to see stars in daylight from the foot of a well was an urban myth. It turns out, that if you know exactly where to look in daylight, and have reasonable acuity you can see Venus by day, if the atmosphere is not too milky with moisture. Venus is the brightest point object. There are a few other brightish objects, which have more difficulty competing with daylight scatter. It is possible however, with a little sleight of hand, to sense signals which are submerging, even well down, in the 'noise'. It will be this method that allows a fix on day light stellar objects.
