Although not being an experienced observer is not necessary to be a member of the BAA or write articles a knowledge of astronomy should be. There are other issues with this article in that the orbit of the Pup is stationary and the Pup itself is at maximum elongation. If the BAA is to be regarded as a serious organization then its website and articles on it need to be right as well and a knowledge of the subject should be a pre-requisite to write about it.. I understand that you wish to make a dynamic website but there must be a threshold before you write.
