These spectacular time lapse images taken with a powerful telescope show the hypnotic flames on the surface of the sun
39-year-old Deddy Dayag used two super powerful telescopes to film the sun's surface over several hours in order to create mesmerizing time lapse videos.
He uses a 152mm achromat refractor telescope, a 200mm Schmidt Cassegrain telescope, and an h-alpha 0.5 angstrom h-alpha filter on a tracking mount to capture sights impossible to see with the naked eye.
Deddy, from Israel, said, "I capture the sun because it is the most interesting and fascinating object that is near enough to explore from Earth.
"The sun, which is a star like all other stars in the universe, is constantly changing and we, as humans living out our lives, don't even notice it. Most of the time we just think of it as a bright light in the sky.
"A few seconds of watching those videos and your entire view of it changes.
"When I reviewed the footage for the first time I was blown away! Literally I shouted with excitement.
"And now, after almost two years of imaging the sun, I can still say that I get excited every time I aim my telescope up there, because each time you don't really know what to expect, each time is a surprise!
"I hope people will watch those videos and understand how small we are compared to our star. Our sun (named Sol) holds 99.8% of the entire solar systems mass.
"We are a grain of dust."
