Episode 156: Chandra

This time we are off into space, but still sitting in front of the monitor. I take X-Ray data from the Chandra Satellite and make a false colour image out of them. All I needed to know for that (and much much more) is on their album page.

The files I have used and the tutorial I was inspired by are also on the Chandra website.

While I was editing this show I thought about some different ways to process such an image. Feel free to comment if you also find something better. I’ll update this posting during the week.

All images used in this posting and the video are made by NASA/CXC/SAO .
