            Light Box:

  • I built this double diffusion-layer light box myself in Dec 2010.  This is used for taking flat frames following imaging sessions in "calibration" steps and is necessary to remove optical system effects and sensor imperfections (common with all modern CCDs) from final images.  It is powered by 9V DC with either a battery or power cable (power controls on opposite side of box in left image, while image on right shows box in use with TOA):
