This “footage” of the moon passing in front of Earth last month is not CGI. It’s made up of images captured over a five hour period by the Deep Space Climate Observatory [DSCVR] telescope. The telescope actually takes 10 shots at a time using filters from ultraviolet to near-infrared. This video was created using shots only from the red, green and blue filters. Each frame thus combines three shots taken around 30 seconds apart, which is why there are slight colored artefacts to the side of the moon itself.
