How to make a light-tight red-light sign box for star parties

http://members.csolutions.net/fisher...tySignBox.html

This website contains construction plans for a simple light-tight box
made from a UPS mailing box. The red-light box is used to display
red-light signs at star parties. The signs are laser-printed
transparencies. The box is designed to screw onto a standard camera
tripod mount. Using such a sign, it is possible to set-up an
informational sign in front of a telescope at a star party that
displays the type of object currently in the telescope. The intent is
to have several of these signs in a line of telescopes pointed at
different types of objects. Using a handout describing the major
celestial objects (e.g. - double stars, dark clouds, open clusters,
globulars, planetary nebula, several types of galaxies), the public can
browse a line of scopes for an orrey of objects.

Attention was given to making the red-light box light-tight for white
light.

Generic transparencies are provided.

This red-light box will be of interest to intermediate amateur
astronomers and to astronomy clubs.

A simple alternative to this sign display box is to purchase a variable
red-LED flashlight from Rigel Systems or Orion Telescopes for $20-$30.
Place paper signs on a clipboard. Hang the clipboard either from your
telescope tripod legs or from a separate camera tripod. However, the
clipboard method may be more susceptible to star party complaints about
unwanted light.

That's a pretty cool idea!

Thanks. Updated to the site, a set of 56 generic transparency-signs
for types of lunar objects. I used the same generic photo for all the
images and did not have time to track down royalty free images that
illustrate each lunar object type.

The sign titles for lunar objects are appended.
