I obtained a detailed profile of Venus from one of my transit images. It reveals some interesting aspects about Venus:



Immediately noticable is how non-circular it is in profile. In addition, note how flat it is in the southwest quadrant as opposed to the south and northeast. Also, you can see huge mountains (at about 5:30-6:0...0 and 11:00) and deep valleys (particularly at 9:00 and 3:00-3:30) and generally a very uneven surface, much more uneven than the Earth is in profile (of course, the profile of the Earth is much subdued because of the presence of the oceans - even so, Venus' profile indicates a huge range of topography). And finally, note that you can see features in the atmosphere, the haze that surrounds the planet in this image. Also note that relative to its size, Venus' atmosphere is much thicker than Earth's, and much more turbulant and uneven in it's apparent thickness. That's one messed up planet, for sure.

It was cropped, and the resolution increased.

Folks, I make a huge mistake. That image is due to atmospheric distortion. I didn't believe it because if it was, it was the worst distortion I've seen. Well, that's exactly what it was. My apologies. I feel very stupid, but I guess that's why they call this "amateur" astronomy.
