Digital camera & Binoculars

Here is my way to attach the pocket digital camera Casio Exilim EX-Z80 to my binoculars Vixen 12×80. It is necessary to cut a piece of aluminum respecting the format of the binoculars, calculating the correct distance between the hole that grabs the camera and the hole to fix with the tripod and the binoculars. Remember to always use British Standard Whitworth (BSW) screw threads, 1/4 inch, and to drill the holes for this width.

This way it is easy to do afocal astrophotography, and get sharp focus, because the camera remains pointed correctly through one eyepiece of the binoculars.

Attaching Exilim to Telescope

Digital pocket cameras like Casio Exilim EX-Z80 are not prepared to be attached to the focuser of a telescope. But it is simple to make a hand-crafted device with a piece of wood and a British Standard Whitworth (BSW) screw 1/4″ thread. The attachment is not rock solid, but enough to take photos and videos through the telescope using the afocal technique. Here we see the Casio attached to the Tanzutsu 114/1000 telescope.
