This shot was produced from 18 images stacked in Registax with a bit of processing in Photoshop CS3 and final colorising to make it more pleasing on the eye.
Original sub's taken with Nikon D300, 300mm prime with 1.4 converter (=420mm), 1/3200s at f8, through Baader solar film.
Main sunspots on show are numbered 1113 (top), 1115 (bottom) and 1112 (the group of small spots at right). Faculae can also be seen near the limb adjacent to the spots. Two smaller spots (un-numbered) can also be seen just above the centre of the disk.
Warning to non-astronomers - never look directly at the sun without proper filters designed for the purpose. Failure to do so risks ruining your camera and, more importantly, your eyes!
