Did anyone manage to get the transit on a camera without Solar/ND filters or welding glass? Whenever I have seen discussions on this subject the successful photographers have heavily stacked filters to reduce sunlight - understandable I suppose as Mercury or other body is so much smaller than the sun from our perspective and, without heavy filtering, it would get enveloped by sunlight much like a motorcycle disappearing between a lorry's headlamps.
I'm not into astrophotography so I don't even know if these photos are possible without a telescope. I occasionally get lucky though, like this evening when I was fooling around on the roof of my house and got a photo of the waxing crescent moon backlit by the sun.

I didn't even know I had captured this until I viewed the photos on my computer. I don't think I could have seen this with the naked eye as the sun was a very intense highlight. Luckily the camera cuts down on a lot of light. I would imagine that photographing a visually much smaller body like Mercury must be much tougher.
