Hello all, Please could you look at the pic in the link below and tell me what you think the marks in the upper right may be. They were extremely difficult to photograph and this is the best attempt out of 20 or so. The pattern covers about 100 degrees in terms of rotation of the lens and extends about 15 - 25% toward the centre. The marks have an odd 'three pronged' pattern and are denser in number toward the outer edges. Is this fungus? http://farm4.static.flickr.com/3440/3278220641_3e0536e5ff_b.jpg Steve.
