Versie 2 van Onze Zon : De meest nabije ster

De afgelopen maanden noteerde ik alles wat maar enigzins te maken had met de zon. Dit met de bedoeling om mijn eerste versie van mijn paper "Onze Zon : De meest nabije ster" aan te passen en af te stemmen op deze nieuwe informatie. Mijn Kerstverlof was er dus aan voor de moeite maar heeft wel geleid tot een nieuwe tweede versie van mijn paper.
Je kunt het werk hier downloaden en ik wens iedereen veel leesplezier.

Orion Nebula M42

Using a different way of editing my astropictures within CS4 gives some nice results. As an example I used a picture of M42 (Orion Nebula). The technic used results in a complete shift of the histogram and taking out some noise.
