The Dutch Open Telescope (DOT), located on Roque de los Muchachos Observatory, La Palma (near the Swedish 1-m Solar Telescope), is an optical solar telescope with a main mirror of 45 centimeter and can reach an 0.2 arcsec resolution for sustained periods. For further optimization of the images, the DOT uses the image despeckle mechanism. One of the successes was the recording of the 2004 Venus transit, the movies recorded can be seen at the DOT website.
