Have you ever run out of battery power while using a DSLR for astrophotography? Orion has the solution! These compact and affordable 12V DC Adapters let you power your Canon DSLR from a 12-volt field battery - the same one you're probably already using to run all your other astrophotography gear at your imaging site.
Compatible with many of the most popular models of Canon EOS DSLR cameras (see below), a 12V DC Power Adapter is a wonderfully practical accessory for DSLR astrophotographers who don't have access to AC power. Just insert the included DC coupler for your particular model of Canon EOS DSLR into the camera's battery compartment in place of the battery, then plug the connector into your 12V DC field battery. Now your camera will stay powered-up all night long, and then some. Each coupler is equipped with a 2-meter cable.
