Photographer Snaps Amazing View of Sun with Hot Telescope

With a camera too hot to touch, an amateur astronomer captured this brilliant image of vast solar filaments winding across the surface of the sun

 “Taking solar pictures such as this one requires you and your equipment to be outside in the direct sunlight. I was trying to use an umbrella for shade and also using towels to help keep the direct sunlight off of my camera and computer," said astrophotographer  Brett Dahl, who captured the image. "The camera was getting so hot that it would literally burn my fingers when I tried to reposition it."

Dahl took the spectacular photo of the sun from McKinney, Texas in August 2012. He used software programs Registax 6 and Photoshop CS5 to process the image. Processing each image took longer than the usual 30 to 45 minutes according to Dahl to bring out the finest details.  

What looks like a cloud hovering over the air is actually a solar filament composed mainly of charged hydrogen gas. The gas is held in the atmosphere by the sun’s magnetic field which gives it the loop-like structure. Filaments on the sun can last for a few days or weeks but a longer one like this may remain over the sun’s surface for a month or more.

WARNING: Never stare directly at the sun with your naked eye or through unprotected binoculars or a telescope. Severe eye damage or blindness can result. You must  always use a proper filter when observing or photographing the sun. Regular sunglasses and photographic polarizing or neutral-density (ND) filters are not safe for use on the sun.
