This adapter allows the use of a 35mm camera body for widefield "piggyback" astrophotography. Remarkable star clouds, meteor showers and whole constellations can be captured on film with a camera mounted atop a telescope in a piggyback fashion. Flat base fits firmly on any telescope tube (You provide the screws. The golden ones in the photo are illustrative and not included) and the mount includes a standard screw (left in photo) to attach your camera. Made from fine finish metal. Specially designed rubber pad (blue) protects your camera base and holds it firmly.
