WHAT KIND OF IMAGES MIGHT WE EXPECT TO OBTAIN?
Near a city, like Baton Rouge, a picture of a galaxy taken with a conventional film camera (left) will very quickly be fogged by light pollution. A digital CCD image of the same galaxy (right) can be processed to minimize the effects of city lights.
A same digital image can be processed to show the faint details of galaxy arms (left) or bright features, such as a supernova, near the galaxy core (right).
The image of galaxy NGC3953 (left) was taken with a telescope that had only a 14" diameter mirror from a location in Clear Lake City, Texas. This city is a suburb of Houston, TX and has much brighter skies than Baton Rouge.
