A photographer has been travelling across North America for the past 18 months, capturing 360-degree panoramas of stars in motion to create a time lapse video of the night sky.

While studying photography at Lansing Community College in Lansing, Mich., Vincent Brady regularly shot panoramas during the day and focused on long exposures of stars once it became dark outside.

"It suddenly became clear that the potential to combine the two techniques could be a trip," he writes in an explanation of the project on his website.

He built a custom four-camera rig complete with fish-eye lens for the project.

After graduation in May 2013, Brady started hitting the road with his new camera.

"My rig has taken me to firefly parties in Missouri, dark eerie nights at Devils Tower, through Logan Pass at Glacier National Park, up the mountains of British Columbia, and around the amazing arches and sandstone monuments in the great American southwest," he writes.

When he travels to a location, Brady says he spends the day exploring for an ideal space to set up for a nighttime shoot.

The cameras then take between 100 and 200 photos each, shooting for up to three hours with one- to two-minute exposures.

Brady edits and stacks the images before manually stitching them into a panorama and tweaking the final product with Photoshop.

The video he created from images captured over the past 18 months shows, among other scenes, the Milky Way setting over the skies of British Columbia from when Brady travelled to Kootenay Lake and captured the Northern Lights.

"It is my hope that this project brings a little more joy to your day," he writes on his Facebook page, where he introduced the project.
