The Celestron site does not say what kind of eyepieces are included with the scope. I am assuming they are some kind of Kellner eyepieces.

As for colors. The lower to the horizon you are viewing the more atmosphere you are looking through. Anything less than 30 degrees above the horizon is going through a lot of air. Take a look at things above 45 degrees and see if you see less of this "chromatic aberration".
