There is a round object in these pictures and I'm not sure what it is. My guess is that it's the moon out of focus but if so I don't understand the ring inside. I did no PP processing other than converting from ARW in DXO (with defaults) and resizing in CS4. Any ideas?

Re: What is it?
Hi Mike,
I can't say really. Shouldn't the intensity of white be thicker if it were the moon or moon behind a circular/round cloud?
I attached shots from a few days ago and no ring effect seems to be visible when the moon is behind a cloud. Maybe it's a typically ring-like /tubular cloud due to wind turbulence much like the people can make when they smoke?

Re: What is it?
It's lens flare created by a single droplet of something like oil or water inside or on the front of a lens, picking up light which is otherwise dealt with by the lens coating. Sometimes this can be caused by a tiny chip in the lens glass (normally the front element, not the back). More often it's a droplet of liquid. The sun is just a bit beyond the lens shade and the field of view in the pic, but still able to shine on to this and cause a small flare mark. The circular effect is caused by diffraction, I would guess you used a small aperture.

My closest guess would be some serious sensor dust. There are several small spots and that big one. Definetaly not the moon. Try to give the sensor a cleaning!
Re: What is it?
In the light of what David just explained, I believe there's yet an other one like that but with less intensity due to its position and place in the frame...David Kilpatrick wrote:It's lens flare created by a single droplet of something like oil or water inside or on the front of a lens, picking up light which is otherwise dealt with by the lens coating.

For what it's worth here are the crops from your photo.

Both were f/22 as I was tring to get the maximum DOF.David Kilpatrick wrote: I would guess you used a small aperture.
The sensor is very dirty, I would normally clean up the sky with with DxO but I wanted to post it unaltered.
