Wild Experiment! Moon thru Screen
by Humanoido
What happens when shooting the Moon through a window screen? This wild experiment shows the beautiful unexpected results - unexpected unless you're already an Astrophysicist, Physics major or remember your high school science class.
What happened? The image shows the screen acts like a prismatic diffraction grating, causing multiple rainbows to appear around the Moon's light.
At least seven rainbows are seen, some are a bit irregular in shape and flanked by reflections. Could the screening be used for spectroscopic studies and more accurate color determinations? Perhaps so by adjusting the conditions - make the screen perpendicular and closer to the telescopes optical axis, adjust the spacing of the screening weave, and use a color-tuned spectroscopic CCD camera without any introduced lenses. The results could be useful in determining the composition of lunar regolith in particular regions on the Moon, in a determination towards finding land for lunar mining and a lunar base.
