Ways of looking at the sun

Tomorrow residents western part of our vast country will be able to observe a rare phenomenon - a solar eclipse. Unfortunately, his "epicenter» придётся the northern part of the Atlantic and the Arctic Ocean, so that the most lucky Iceland. But we will also be something to see - for example, in Moscow there will be a phase of 0.65.

The last time a total solar eclipse was observed in Russia August 1, 2008, and the next time will have to wait right up to March 30, 2033. So catch the chance, ladies and gentlemen, it falls infrequently. If you live in the depth of the eclipse covered areas and firmly set out to observe this phenomenon, it is recommended to prepare the material and technical base. And in fact, as the proverb says, at the Sun through a telescope, you can see twice in your life - right and left eye.

As you know, the naked eye look at the eclipse is strongly discouraged for safety. Of course, some time in the "midst" of the eclipse, it is permissible so long as the vast majority of closed area of ​​the solar disk. But in the initial and final phase is better to use protective equipment. Let's start with the fact that in any case Do not use without filters
Do not expect to do conventional sunglasses, they will not protect your eyes. Any methods since Mihailo Lomonosov like zakopchёnnogo glass is also not recommended because of the low efficiency and unpredictability. Ideal - special solar filters. They can be purchased in stores of goods for astronomy. But remember that if you put a filter or primatyvaete to the eyepiece, it can overheat and melt / burst. To avoid this, cover the lens unit opaque cover, or "native" or made from scrap materials. As an option - install filter in front of the lens, then nothing will need to be closed. Yes, and forbid you from shooting eclipse on any photo equipment without a filter.

Life hacking number one:
Life hacking number two:
Life hacking number three:
And again, when observing astronomical phenomena and celestial bodies always place the unit on a tripod. With more or less marked increase, from 20-fold or more, even snuggling binoculars or a telescope to the window frame or a tree does not help: we are beings living and pliable, can not apply at the time of the rock, so all our micromotions quickly will lead to that you just seasick. Yes, and look at the details on the shivering object in the eyepiece will not work. In general, no pleasure, confusion and a missed opportunity.

By the way, most of the multiplicity of you do not need enough 20-60. And the large diameter of the front lens is also not required, still look at the sun, catch the rare photons do not need. Good Luck! And a nice observation. :)
