![]() To achieve a spiral star trail effect using this method you need to go to an unobstructed area that has very little light pollution. I personally prefer the LRTimelapse method that has become a popular alternative to achieve the vortex star trail effect. Some people were using adobe after effects or photoshop to make the spiral star trails. It wasn’t long until other people started to discover alternate ways to create this effect. Finally I achieved the effect I was going for! If you would like to see a parts list and detailed instruction guide to build your very own slow zoom machine please check out the links below. This setting allows for you to take a long exposure, then lens would rotate a small fraction of an inch and then the camera would shoot again. I realized I could not let it rotate at a constant speed so with the help of a MX2 control box I was able to shoot move shoot. Everything was starting to come together nicely, however when I went to shoot a long time lapse of the night sky to get the vortex star trails my camera was rotating way too fast for the effect. I also needed a lens gear (a gear that wraps around the lens) which I found on amazon, sold by. ![]() ![]() To my surprise, it worked perfectly and I was able to get all the gears in alignment. I owned a sunwayfoto rail which helps me with panorama photographs and I decided to try and attach an aluminum channel to it. They sold these aluminum channels which have many attachment points to hold practically anything you can think of. I came across which sold robotics parts and mostly everything I would need to build this motorized machine. I knew I needed a motor, some gears and a way to control the motor, however I didn’t know how I was going to attach the motor to the camera lens. When I built this machine, I had no instructions and it took me about two months of trial error before I got it to work correctly. I highly recommend you check out his work, as he is my inspiration to further progress my night work. An idea I got after seeing an amazing photo by Lincoln Harrison incorporating vortex star trails who said he used a rotating machine for his image, so I knew I had to build one. The short answer was, I used a motorized slow zoom machine that I built to rotate my Nikon 14-24mm lens. When I created this photo I had many photographers asking me how I made the effect.
