Dear Friends,

I intend put some demonstrations of celestial mechanics and fundamental astronomy in the following site: bramon.org It is an organization of amateur astronomer that are doing a great job in meteor detection and astrometry. So as I decide help this network, I think to share the beautiful and didactic astronomy demonstrations. For instructions purposes I d like to know the possibilities , and if there is any implications for authoring issues etc..

Of course, any demonstration will have the citation and the link sources.

Thanks.
