Weekly Photo – Star Trails.
Each photo has a 30 seconds exposure time, i use duct tape on my shutter button so the camera takes one shot every 30 seconds and i just let it fill up my SD card. So this shot took several hours and was ok since the camera took the shots when i was sleeping. The software puts the trails together with no effort, would not recommend to do this manually. So to get full frame star trails like this it takes about 400 photos or 3 hrs.
