Lightbox and flats question
I have all the bits to build a lightbox, except the skills to wire the electronics.
I was wondering in the mean time, if I simply place the defuser screen in front of the OTA and point the scope skyward in daytime (not near the sun) could I use natural the light to generate the flat?
I know that I am not to change the focus between taking the lights and the flats.
