In this video, I explain (using a bunch of timelapses) why polar tracker or star tracker camera mounts allow you to take long exposures of the sky without streaking. I also show off my polar tracking rig, which is my most recent piece of homebuilt photography equiment. It uses a door hinge and a curved lead screw to slowly rotate the camera (approximately 0.25 degrees per minute) and eliminate streaking in astrophotogrphy images. • Based on the design by Gary Seronik: • http://garyseronik.com/build-a-hinge-... • My parts: • Motor: https://www.amazon.com/gp/product/B00... • Gears: https://www.amazon.com/gp/product/B00... • Battery: https://www.amazon.com/gp/product/B00... • lead screw: #8 threaded rod from Home Depot • Hinge: 8 x8 strap hinge from Home Depot • Controller: LM317 configured as voltage source • Any USB battery will work - this is just the one I have for my phone. • If I re-built the design now I would probably print or lasercut the two necessary gears to save money and have more customizability. • • Music in this video: • I dunno by grapes, is licensed under a Creative Commons: Attribution License (https://creativecommons.org/licenses/...) • Source: http://ccmixter.org/files/grapes/16626
