Talk about "As the World Turns": A sped-up video of Earth spinning through space shows a dizzying array of clouds and continents from a satellite located 1 million miles 1. The time-lapse video of 3, images shows pictures taken every 2 hours. The satellite is located at a gravitationally stable spot in space between the Earth and the sun known as a Lagrange point. The first picture from this spacecraft was sent on July 26, , EPIC's lead scientist, Jay Herman, said during the video's narration. From EPIC's vantage point hanging in space, the instrument records images in 10 different wavelengths. Those wavelengths of light are then combined to create an image close to what the human eye would see. The video slows down briefly to show the moon's shadow racing across Earth in March , during a total solar eclipse. The spacecraft also records the sun rising and setting about 13 times each day from itsthe satellite's perspective.
A couple of nights ago I was lucky enough to have some decent seeing conditions to image Jupiter. I was happy I did. I like this semi-manual approach, as it gives you lots of control, and involves lots of fiddling around with image processing software. But it does take forever though. Here is my latest result: Mars imaged on May 17 under pretty good conditions well, for Dutch conditions of course. Processing the data took quite some time: out of 50 recordings I wanted to select only the most promising ones to then further process using AutoStakkert! To this end, I first let AS! The best recordings were then processed more carefully using AS!
