Best intervalometers for astrophotography | Space

An intervalometer is a clever piece of kit that automatically presses your camera’s shutter release button for you. It doesn’t do this with a robotic finger, although that would be worth seeing, but using a small port on the side of the camera body that gives it access. You can program them before you start shooting, and leave them to do their job while you get on with something else, which in the case of astrophotography projects may well be sleeping.

Increasingly, intervalometers are being built into camera firmware, meaning the distinctive little black boxes on the end of cables sticking out of the side of a camera are becoming less common sights. However, some of the best cameras for astrophotography don’t have them built in, so acquiring one is essential for star trail images, time-lapses, and much more.
