Description

This image of the Great Orion Nebula, Messier 42, with De Mairan's Nebula, Messier 43, is my first attempt at making a composite image, and also my first attempt at a mosaic image. It is a composite of three sets of different exposures for the bright central areas of M42 and M43, plus an additional set of exposures centered further south (down in this image) mosaic'd with the other sets to show more of the faint nebulosity. I then increased the saturation of the colors more than I normally do because I felt it really adds to the impact of the final image.

The mosaic turned out perfect I think, and I will definitely try a 2x2 mosaic of some larger object at some point. I'm not as satisfied with the areas of the image affected by the compositing, but I think its a good first attempt!
