Photo of the Week for December 6, 2013

During the summer months, when sunlight lasts late into the evening, some astrophotographers turn to shooting the closest star to us: the Sun. Jean Guimond of Quebec City created this incredibly detailed mosaic of the Sun from images captured on July 27, 2013. Using a newly acquired Lunt LS80T/PT Hydrogen-alpha f/7 solar telescope equipped with a Takahashi 1.6× extender and a Lumenera SKYnyx2-1 monochrome video camera, Guimond combined six separate images, each created from the best 100 frames (of over 1,000 taken), and processed and aligned them using AutoStakkert!2. More processing was accomplished using Adobe Photoshop. North is up and west to the right in his image.
