Filmmaker Gavin Heffernan didn't use any special effects to make his trippy "Dreamlapse" videos in Death Valley National Park, just long exposures on his DSLR cameras and plenty of boxed wine.

This week, Hefferman's "Part Two" of the Sunchaser Pictures Dreamlapse series was released to the world, and based on the surreal images he captured in the desert in the middle of the night at Racetrack Playa Lakebed on March 17-19th, part two will likely go viral like Part One did when it was released in January.

Death Valley is a crazy place to shoot at," Heffernan told National Geographic in an email. "The horizon is so strangely uneven/malleable. I don't know if the valley was cut by water or underground magma, but it's almost impossible to find a straight horizon. In many cases it took me 5 to 10 times as long as usual to try and 'straighten' the camera."

The activity of the Sun made a cameo in part two as well. As EarthSky suggests, "Look for the pink aurora during the star trails shot at 1:36 and later in more detail at 2:22. This aurora was made possible due to a CME that happened the night of March 17, 2013 and is a rarity at latitudes as far south as Death Valley."

The videos were made with minimal equipment. As NatGeo reported in January:

"Armed only with boxed wine, firewood, and our DSLRs, we had to conquer epic climbs, sand roads with the 4×4 Jeep, and the occasional UFO," Heffernan wrote on Vimeo. "But it was all worth it when the skies cleared and showed us an incredible galactic palette! Star Trails shot at 25 sec exposures. No special effects used, just the rotation of the earth's axis."

Heffernan recommends watching the videos in HD with the volume turned up on your headphones.
