Hi I am a regular visitor to S&T website and use their interactive star chart a lot. I want to incorporate similar functionality in my outreach website. The chart used by S&T looks similar to Heavens-Above type. Can any one guide me where can i find information for the same and also to any tutorials and sites that allow using interactive starcharts for free for outreach. Also please let me know where can i post this question - if this is an inappropriate section. appreciate your response.... Clear Skies Harshal
