lightbox overall
Light box for flat fielding DSLR and CCD images.
Made from 1/2" foamcore, white tape, foamcore screws (the clear plastic dots you see near the edges and corners. Hot glued at all seams. White taped at all seams.
Base and top are 15" square; sides are 20" long.
Item at left in bag is a photographer's light diffuser, like a shower cap made of even-density translucent white nylon.
This stretches over C-11 telescope front-end when shooting twilight flats instead of using light box (which is NOT very portable).
Bulbs are appliance light bulbs, 10W, and there is one in each corner.
