Star Trails
(click here for a larger view)
In this example I captured night time star trails with two shooting stars.
For this picture I used the following components:
- Camera
- Universal Photo Timer.
- Clear night sky.
The Universal Photo Timer was used to activate the camera for a 20 minute exposure.
If using a digital camera for bulb exposures, the camera may perform a noise reduction which could take as long as the actual exposure.
