Light Box

So I found out about these things called ElectroLuminescent Panels on the QHYCCD Yahoo forums and it provided for a convenient way for me to build a light box. Bought an A3 size EL panel from glowhut.com, which was shipped quick and courteously. Went to Michaels and bought two foam boards (16"x20") and made this:




I cut the foam board crudely, to be slightly bigger than the A3 EL Sheet. Cut a hole in one of the foam boards such that the dew shield fits through it snugly and then sandwiched the EL sheet in between the foam boards so the black side is outside and stuck the foam boards together with super glue. Voila! there's a light box!



It provides nice even illumination...



through the dew shield :)



The depth provided by the foam board with the hole is good enough to hold the board even when the dew shield is tilted and hence I should be able to mount this on the dew shield while the telescope is mounted on the mount. Just have to make sure that the telescope is pointing towards the zenith. I am excited to try this out. My primary problems so far have been light pollution gradients and bad flats. This should definitely solve the latter.
