North Korea missile: Inconsistencies spotted in Hwasong-15 images

 

 Langbroek, who is based in the Dutch city of Leiden, said he's been studying the photos since they were released by North Korean state media last week. Something was off; to shoot stars, photographers use a longer exposure to more let light in. However, the longer exposure means that movement is captured as a blur. When photographing a missile at night, photographers would use a wide-open aperture and fast shutter speed to capture the missile's rapid ascent. Stars wouldn't show up that clearly in an image, even in North Korea, where there's very low light pollution. "They looked so crisp, that just didn't seem right to me," said Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center
