Throughout July, Comet NEOWISE has been visible to those in the northern hemisphere as it orbits the sun. Portland-based photographer Lester Tsai recently traveled to Mount Hood to capture the phenomena as it shoots over Oregon’s highest mountain in a remarkable set of images. One of the brightest comets in decades, NEOWISE won’t make another appearance in the inner solar system for 6,800 years.
Tsai recounted the experience, describing the necessary preparation and the efforts to determine the frozen object’s probable visibility. “The comet changes position each day but when I mapped it out, it looked like there was a good chance it would do what I needed it to. I had never been there (Mount Hood National Forest) before but was excited to check it out,” he shares with Colossal. Location is crucial for astrophotography, but factors like weather, the sun’s position, and the moon’s cycle have an effect, too. Light pollution from a nearby municipality also can brighten the sky too much for a clear shot.
After traveling through a dense forest in the middle of the night, Tsai found his spot on a nearby cliff and set up his equipment. “Based on the rough directional data I had, I knew the comet would rise to the left side of the mountain and make its way up and to the right. Because this was such an unprecedented and possibly once in a lifetime event, I decided to use one of my cameras to shoot a timelapse,” Tsai says.
He expected the comet to arrive around 2 a.m., and after waiting and worrying he’d missed it, NEOWISE finally made its appearance an hour later. “As the night went on, the sky began to slowly brighten and saturate with beautiful colors on the horizon. 3 a.m. passed, and as 4 a.m. arrived, the comet was almost directly over the mountain,” Tsai says. Thanks to his patience, the photographer was able to capture the fleeting body as it descends in the star-speckled sky.
