Scientific paper

This paper discusses the ability of repeated CCD images of the same star fields taken with CCD to discover new variable stars. It results that more than 90% of variable stars brighter than 12 magnitude have not yet been discovered. Here we propose a project to search for new variable stars down to magnitude 15 using instruments with diameter equal or greater than 8 inch and amateur CCD to perform such survey: applying a median filter through 3 consecutive images, slightly shifted among them, an accurate survey avoiding mistakes can be performed.
