Atmospheric detail?

Hi Folks, since the weather has returned to normal over here (cloud & rain), I have tinkered with some of the images I took of Venus through the EP on the 11th. I took the 24 best shots (out of a total of 78), cropped and aligned them, then ran them through Registax. Finally, I flipped the image to get the "actual" aspect. Incidentally my first-ever attempt at image stacking.

Consider the image below. While far from "astrophotography" level, I did notice an interesting detail. There is a lighter patch around the 11 o'clock position. Initially thought that this may be an artifact of some description, however when I looked at your images Shah, I did notice a similar area at about 8 o'clock. The question is now whether your images are erect & round the right way. Their orientation suggests this. If they are, we may just have recorded some Veneral cloud detail - either an area of higher albedo, or higher transparency, depending on whether it's refracted or reflected light. And if so, I'm sure it's the size of Australia

Interesting, if nothing else.
