PHOTOGRAPHING THE SUN

Solar astrophotography can become a simple and enjoyable matter with the right equipment—an aperture solar filter, an adapter to couple your camera to the telescope, and preferably, a telescope mounting that can track the Sun.



Some amateurs take a photograph of the Sun every clear day, building up a valuable archive of images. Others photograph specific solar activity, such as sunspots, or use narrow-wavelength filters, such as H-alpha.filters, to capture the active surface of the Sun.

The Sun's brightness means you can use slower films—with speeds of ISO 25 to 100—which provide better resolution. If you prefer black-and-white film, Kodak's Tech Pan is ideal for solar photography. Solar filters reduce the Sun's brightness to about that of the Full Moon as a guide to exposure times for solar photograph, but take a few test rolls to see what works with your equipment.

Experienced solar photographers knows that the toughest problem to contend with is poor seeing. Shooting in the early morning or accross a body of water can help, but part of the challenge lies in discovering what works best for an individual site.
