O.K. so this animation of a cactus flower opening overnight doesn’t look like it has a lot to do with Star Vistas – BUT – I can use the same technique with the Canon 40D and the TC-80N3 timer/controller to do the same thing with night sky images.  So the idea is to get the 15mm fisheye lens on to the Canon 40D – point skywards – and then take a sequence of sky shots and see what we get.  This is going to be an extremely interesting experiment :)
