Well i literally slapped this together tonight. It needed to be able to provided flats for an 8" scope in the field, be
light and cut down stray
light. Ok I seem to have found an answer LOL.
this is it, a thin sturdy
box i scored from Alan that used to hold t shirts, using a a3 size thin
light sheet, left over pluck foam, duct tape and drafting film that i managed to score from work (with computers and plotters this stuff is like gold - expensive and hard to find), and black foam core board.
used the cover of the c8 to cut out the circle in the foam core board, then cut out three sheets of drafting film and stuck over the hole with duct tape, then duct taped the pluck foam to one side and also taped the
light sheet to the bottom of the
box, then placed foam core and hole over the top and taped in. the pluck foam keeps it at an even height.
next turned it on and gave it a test shot with a canon ixus 80IS .
i seem happy enough, just need to get some contact to make the outside moisture resistant and use some black ripstop and a
light shield and it will work in the field.
forgot to say but it is powered by 12 volts
