observe the Sun without proper precautions can be extremely dangerous.
To observe visually or photographed our star systems are very different. The easiest by far is nell'apporre OF NEXT MAIN ALL'OBBIETIVO of telescopes and binoculars SUNSCREEN an appropriate certificate to that effect by the manufacturer and full technical specifications and instructions.
NEVER use filters that must be placed solely on the eyepiece of telescopes and binoculars. They are dangerous.
to the need to use a different number of filters at the telescopes, photographic objectives, but also small direct-vision goggles eclipse, with a preference to use the material called "Astrosolar" produced by Soc Baader Planetarium in Germany. A thin film to be treated with care and who is able to effectively mitigate the sun's rays that reach Earth. Its small thickness does not affect the main objective optical precision. It lends itself to being placed in cells or pre-built, after cutting, in cells made of small craft projects that are to be set at different telescopes, photographic objectives, hunters, etc..
The color is silver and the sunlight will be white. Good for the observations of sunspots, even at very high magnifications. The Maksutov 127 mm. sometimes I was able to reach many veramnet magnification, so surprised and pleased.
filter dark in the photo is another product instead. The Sun sees orange, but the quality is much lower.
