Photo of the Week for August 15, 2014
More and more visual observers and astrophotographers are purchasing equipment specifically designed for viewing and photographing the Sun. While most solar filters allow observers to view sunspots, specialized hydrogen-alpha solar telescopes reveal details of flares and prominences erupting on the Sun’s face.
Andrew Kwon of Mississauga, Ontario, recently made this four-panel mosaic using a Coronado SolarMax II 60-millimetre hydrogen-alpha solar telescope and a ZW Optical ASI120MM camera. He captured and digitally stacked 1,500 individual frames for the disk, and 1,000 for the prominences.
