Hi West

Why don't you try to run up the camera inside and see what image you
can get out of it.
As the other posters hve said you will be unlikely to get gamma rays
from space, but you may be able to image something even if its not
gamma. Can you change the length of exposure?
If its so sensitive to temperature fluctuation, you had better wait
for overcast outdoor contitions before you take it outside.
