I took this picture last night close to sun set. Her nest was nearby and when she saw me approaching, she came out of the nest and circled me several times. I took about 30 shots then left the area. She obviously didn't want me there and I'll stay further back from now on as it looks like the pair of eagles will be raising a family soon.
She flew in very close to me. I wish I would have had time to take the 1.4 teleconverter off , she was that close.
Thanks for looking

The halo is quite noticeable. I've never seen a halo from just reducing the size of an image as Ron Bielefeld suggests, and sharpening is unlikely as the reason unless the parameters used were much different than I use. I suspect the halo is the result of exposure tweaking on the eagle that spilled out into the sky.
I think the halo is a result of my poor sharpening technique. I used unsharpen mask after I had cropped and resized the pic. I have redone the image and I think the halo is gone in the new image. I'll post the redone image in small format and try to put a large sample in my Gallery.
When you say Halo are you referring to a sort of white outline around the edges of the eagle.. i.e. the shoulders of this bird when too much sharpening is applied or is a Halo a brightness extending out from the subject into the sky. ?
Thanks again

you got a superb flight shot!
The second image you posted does have a rather large halo, but it is also only 65 KB's, which means it was compressed much more than the original image you posted which is 189 KB's. Compressing an image that much is going to cause loss of detail and possibly artifacts.
When sharpening it is best to selectively mask the areas that need to be sharpened and then only sharpen those areas. I highly recommend not sharpening the sky.
Thanks again;
