Hello, first time writer with some questions.

Two weeks ago I was at the monthly meeting of the Amature Telescope Makers of Boston at MIT in Cambridge. The speaker of the night was from the AAVSO (Arnie Perhaps?) Anyhow, as a novice I was intrigued by the whole presentation on variable stars and amazed I could follow most of it. There was one thing however in the presentation that I thought was really intriguing- it was an animated .gif of a star cluster (m92 perhaps?) that showed the animation of the variable stars in the cluster- I was hoping to see it again, and if possible share it with friends if it were available, anyone know where I might find it?

Thanks in advance
