Are there divisions between amateurs and professionals in astronomy?
One thing about astronomy is where amateurs and professionals meet. Just about one of the very few sciences where professional-amateur collaboration really means something. Amateurs carry out very valuable work and it is valued by professionals. So be glad we have the Privileged Astronomical Association made of amateurs and professionals and the Royal Astronomers Society professionals and amateurs; its all mixed up. And then there are things where amateurs and professionals meet. Its very valued pledge.
