Of course, there are five years of development between the Canon 550D and my old Canon 350D. Looking through my photos I noticed something interesting. The brightest star trails had a blue line on one side and a red line on the other side: Chromatic aberration! Sure, it is not a desirable effect, but it was actually kind of cool to see something I have learned about in class. :)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I have bought a new camera: a Canon 550D with the infrared filter removed.
