Abstract

This paper is designed for the variable star observer who uses a telescope in the aperture range of 3 to 10 inches. The assumptions shall be made that the observer's eyesight is normal and that the instrument is of good optical quality and mounted in a stable manner. furthermore, it shall be assumed that the observer has had some experience in variable star observing and that his observing conditions are sufficiently good to allow him to see fifth magnitude stars or fainter with the unaided eye on clear, moonless nights.
