Abstract

The purpose of this paper is to discuss the daytime tracking of astronomical objects. We are interested in this because many stars are not visible in the night sky, or we may want to perform around the clock observation of other astronomical objects. Daytime tracking presents many difficulties, including high sky background levels and low object to background contrast. In this paper I will describe a daytime tracker experiment, give a description of the various components, and talk about the bandwidth requirements and performance of the system. I will discuss the contrast and background problems as well as the use of video processor boards to mitigate these problems.
