Only clear night for the past 2 weeks - great transparency, so got some images - first one of the Omega Nebula.

As usual, nice image!
I'm trying to make out the swan. Is it upside down and facing 2 o'clock?
Probably that's all we can see visually. BTW, is that dark patch on the right a cloud of dust?

Thanks, Rich and Weixing, yes the swan's base is at 11 o'clock. Also, very well spotted, Rich, the black bit at the neck of the swan is a dark cloud. I was adjusting levels on the image when I noticed that in that area the light levels were lower than anywhere else on the image - even to the edges of the image. Checking out much deeper images of the swan showed this to be the case. So, on this image the nebulosity extends almost everywhere, but there is this deep black cloud in this location.

BTW, just finished another image from the same clear night - the Eagle nebula;

Not as long an exposure - object passing culmination, and had dew problems, so a bit more noisy.
