The Sun on 12/12/12

At this time of the year, the sun is in the trees from my observation site even when it is highest in the sky. You can see the tree limb shadows in these shots.  The first is a processed stack of 200 of the best frames from a 1117-frame capture (640x480).  Tree limbs cause stacking and alignment problems (the linear artifacts in this image)

This next image is a processed single shot from a 1000 frame AVI. The sun was deeper in the trees in this shot and  Registax could not produce a coherent stack.  There were some nice prominences and filaments visible.  Images with PST, SolarMax II and Microsoft Lifecam,  This image is a crop from an original image of 640x480 pixels.
