Wide Field Images
Most of the images I take are of very small areas of the sky, i.e., a fraction of a degree, and show
the details of the object in question. But larger scale images of some areas of the sky, showing
several degrees, are also very interesting since they show the relationship between the various
objects in a given area. These images are normally taken with a camera lens (50-200mm).

This is an image of the area around the star Antares (orange star on the right) in the
constellation Scorpius. It shows emission nebula (red), reflection nebula (blue) and a large
area of star obscuring dust. Several globular clusters are also in this area, the largest
being M4, shown above Antares. The image was created from 10 x 4 minute exposures
with a modified Canon XSi (ISO 1600) and a 200mm lens at f/3.2. The width of the image
encompasses about 6.5 degrees of the sky. This area is on the edge of the Milky Way
which is evident from the thousands of stars present in this image.
