Subject: solar mosaic reattacked!

Thanks to Brian, Alan & Milton for helpful comments on my first solar mosaic.

So I reduced the focal length back to 1000mm and seeing was better today as well.  Uneven field illumination is still a problem which I tried to mitigate by creating irregular borders between the mosaic pieces.  More mosaic pieces with greater overlap would also address this problem but I'm a little leary of taking on a hundred piece mosaic.  There were also many interesting surface features which made aligning the pieces easier.  

If you view it at 100% size the detail is quite good and you are less likely to notice the brightness of the seam regions.
