But there’re simpler options if you’re looking to get some shots tonight. Even in the video after the break, it looks like the clock may skip a few steps on the way down as the weight of the camera starts pushing on the gears. The GoPro (and other “action” cameras) should be light enough that it’s not a big deal but don’t expect to mount your DSLR up to one. It was intended to move an hour hand, not your camera, so it doesn’t take much to stall out. If there’s a downside to the clock movement, it’s the fact that it doesn’t have much torque. But a clock is a device that’s essentially been designed from the ground up for keeping track of the planet’s rotation, so why not use it? Sure you could do with a microcontroller, a stepper motor, and some math. Using a 24 hour clock movement is an absolutely brilliant way to synchronize the camera with the Earth’s rotation without the hoops one usually has to jump through. The result is a time-lapse where the stars appear to be stationary while the horizon rotates. It keeps things simple by using a cheap 24 hour clock movement to rotate a GoPro as the Earth spins. We’ve covered cheap DIY star trackers before on Hackaday, but this design posted on Thingiverse by is perhaps the easiest we’ve ever seen. Another experience you’ll miss out on.īut in reality, dramatic results don’t necessarily require sticker shock. You shake your fist at the sky (since you have given up on taking pictures of it), and move on with your life. Astrophotography is one of those things you naturally assume must be pretty difficult surely something so awesome requires years of practice and specialized equipment which costs as much as your car.
