Stunningly beautiful Sun photographs taken by an amateur photo by Alan Friedman in the courtyard of his house in the city Baffolo, USA.
Friedman removes the sky from his yard in the center city, Buffalo, NY. Thus, the typical candidate for celestial photography, such as galaxies, nebulae and distant star clusters are not available because of the urban world. But the sun - is completely visible and accessible object in a pure clear sky.
October 20 Friedman connected to its own Hydrogen-alpha telescope filter that selects a tiny piece of the visible spectrum. Hydrogen, the main component of solar radiation is strong in this dark-red light, allowing you to display the outer layers and flare extending from the solar disk sharply and in detail.
Friedman said, A few years ago, this type of filter has been available only to large research telescopes. And still it is not cheap - the filter cost to the author pictures in 5000 dollars. His telescope Friedman calls the "Little Big Man" as having a small size, he has great abilities. Lens Telescope has a diameter of 3.5 inches (about 9 cm).
Instead of just making some shots, Friedman took 90 seconds of video and chose only the clear images. Each exposure recorded the approximately 900 personnel, but after selecting the photographer had left only the top 200.
