As a matter of fact, I searched a variable star at the reported position in IAUC ;-) From your page, I learned Comet Williams was discovered during the variable star observing, am I correct? If correct, I think this glorious byproduct of variable star observing should be better known by the variable star community. Although the story on the first Tilbrook's comet is now widely known, I haven't read other than your page about how vairable star observation contributed to the comet discovery on Williams' case.
