Smiley on the Sunshine Coast

What an amazing sight. I'm sure there will be many more but here it is.

P>S. I shot with canon 400d which has only yesterday had this strange shadoe appear on the corner. It also appeared through my scope but tonight I only shot through the camera which I supose means my scope is OK. Any ideas.

Mark :)

Nice shots Mark. The shadowing in the corner is vignetting. You use flat fields to get rid of that (when imaging through the scope).
