  Sun Sun: Astronomy: Sun - THE SOLAR SCOPE

THE SOLAR SCOPE

A solar telescope does not need much aperture—6 inches (150 mm) is ample, and good observations can be made with apertures of 2 to 3 inches (50 to 75 mm). Because sunlight usually creates poor seeing, cannot use the higher resolution afforded by a larger scope.

  Sun Sun: Astronomy: Sun - PROJECTING THE SUN

PROJECTING THE SUN

The other technique used for solar viewing is projection. It requires no costly equipment and allows a group of people to view the Sun at one time. Aim your telescope at the Sun and affix a sheet of white cardboard behind the eyepiece, focusing until the image looks sharp.

  Sun Sun: Astronomy: Sun - PHOTOGRAPHING THE SUN

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.

  Sun Sun: Astronomy: Sun - THE NEAREST STAR

THE NEAREST STAR

The Sun is our closest star—in fact, it is about 270,000 times closer than the next nearest star, Alpha Centauri, and is the only star whose surface we can see in any detail.

  Sun Sun: Astronomy: Sun - OBSERVING THE SUN

OBSERVING THE SUN

Life-giver, and even law-giver in the past, the Sun has a strong influence on the world that anyone can feel on a sunny day.
