What's the difference between 一番星 and 最初の星?


What's the difference between [一番星]{いちばんぼし} and [最初]{さいしょ}の[星]{ほし} ?

Do they both mean _the first star_ in the same context?




Only 一番星 means _the first star_.  
If you call me up and say ''最初の星を見つけた'', I may not understand what you
mention. I may wonder if you're looking in a new telescope, or you have
researched the oldest star in the universe.
