You’ve probably seen star trail photos before, but how about a “moon trail?” A Finnish photographer named Janne shot this beautiful photo earlier this week as the rising moon streaked across the sky. Janne was shooting with a Nikon D800 and 100-300mm lens at 300mm, f/8, and ISO 100. The trick behind the shot was a 10-stop neutral density filter, which greatly cut down the amount of light hitting the sensor and allowed Janne to shoot a 2258-second exposure — that’s a whopping 37.6 minutes!
Here’s a closer crop showing details of the moon trail:
