I have captured many Meunch stars but never observed this phenomenon. I believe that the light from the star underwent a second diffraction as it encountered the sharp edge of the bark diagonal to the upper right corner of the sign. The story behind this capture has been posted here (http://dgrin.com/showthread.php?t=132835) but I thought the folk on this forum would enjoy the image. I am also interested to see other examples of this that you have captured (or to hear an alternate explanation.

Beautiful prayer and a beautiful image. I don't completely understand the defraction thing, but I can appreciate it.

Jack,

Very good choice of flares for this scene:D

I enjoy the prayer, having traveled through many woods myself.


Regarding the flare, I noticed that particular lens lends itself to some amazing looking flares because of its rather large outer element. The light is bounced between the second element and back into the inner surface of the outer element, or that is my guess. I have scene this in underwater housings where the housing dome usually 8" in diameter does the same thing.

If you take that lens and shoot straight into the sun at F22 you will see what I mean:deal

Thanks Mark
Not sure if that's what happened here as I've shot some other stars with this lens and not seen this effect.
