Abstract
Now that a brief history of solar observing has been given, we are almost ready to move on to the meat of solar observation. First, however, tools must be discussed. This is of great importance for an amateur’s outcomes, and it is a safety issue as well. Imaging the Sun with safety in various wavelengths and bandwidths has evolved substantially since the first attempts in the 1800s, and now requires the application of some very precise filter coating technologies. These sophisticated filter construction requirements can lead to expensive solar telescope designs.
