Thank you all for the help regarding the aurora experiment. I know have a
few things to test and deviate from. I now have a question about parts. I am
looking for an inexpensive source for iris diaphragms. Something between 60
and 100mm diameter would work best. I am also look for something that is
relatively durable. I needs to last a month on the floor.
