Mercury and the Sun

A little black disc against a big bright disc: Mercury (lower left) wanders across the face of the Sun. The fuzzy patch in the upper part is sunspot 2542.

My original idea was to dig out my solar filter and attach it to one of our SLRs, but that meant trying to work out which box it’s stored in. It was much easier to simply project the image onto a white sheet of paper. Having said that, it took a few attempts to get the camera to focus on the image, and then angle the paper so that it wasn’t too shiny (it’s amazing how shiny paper is when projecting the Sun). I was also impressed with the camera’s resolution, even showing up the fibres in the paper. With the breeze and heat haze from the Sun itself, it took quite a few photos to get a handful that were sharp enough to show. This is one of them. Obviously 🙂
