The Sun in 2010
As mentioned in the main page for the Sun, it was emerging from an unusually deep solar minimum in 2010, which coincided with the time I started imaging our closest star using a Hydrogen-Alpha filter. Interesting surface features were few and far between during this period. Unless otherwise stated, all images were shot with a Lunt LS50 filter and BF1200 blocking filter on a Borg 76ED telescope. The telescope was mounted on an Astro-Physics AP1200GTO mount. Camera used was an Imaging Source DMK 21AU04.AS camera. A Celestron Ultima Barlow was used to zoom in on the few interesting surface features found. Images were captured in monochrome via IC Capture, then stacked using AVIStack and colorized in Photoshop.
