Venus Transit Through Clouds
A shot of Venus transiting the sun, taken on a tripod and using a 10 ND filter for safety. With the clouds it was hard to get a clean shot, but Venus is clearly visible, and even a few smudges of sunspots can also be seen.
The manual lens doesn't report actual shooting parameters - the actual aperture was around f/8, using a Pentax Tele Takumar 400mm f/5.6 manual focus lens on an adapter as my 'scope'.
