Once again, my 'five for a Dollar' coasters
come into play. by raising the edge of the dome and keeping the object
level, I can shoot at most any angle. The Cloud Dome is exactly 39.5
centimeters in Diameter at the base. By raising the edge 3.44
centimeters, I elevate it exactly 5 degrees. Since the Sine of an
angle from zero (0) to forty (40) degrees is almost a straight line, raising
the edge of the Dome by multiples of 3.44 centimeters , raises it 5 degrees
at a time.
(Trust my math, I'm a physicist...)
This picture has the dome raised at 7 centimeters, or at eighty (80)
degrees. Raising it 14 centimeters changes the angle to seventy (70)
degrees.
This leaves an opening at the bottom where stray light or hot spots might
creep in.....sooooooo........
