13 minutes and 39 seconds to be exact. That’s how long the shutter was open pointing at the North Star tonight. It was great finally having a clear night I could do this! I’ll be trying much longer times to see how long I can get the star trails. The bright area in the lower left is light pollution from a nearby town. It’s hard to avoid in New England 😦
Taking long night exposures is very time-consuming: first you have the actual time the shutter is open, then over twice as long (it seems) for the camera to conduct noise reduction processing. But it’s worth it, IMO. Enjoy!
