context_page_description: The Dutch Open Telescope is an optical solar telescope located on Roque de los Muchachos Observatory, La Palma. With a main mirror of 45 centimeters, it can reach an 0.2 arcsec resolution for sustained periods. For further optimization of the images, the DOT uses the image despeckle mechanism. It was used to record the 2004 Venus transit.
  The open design was a departure from vacuum-style solar telescopes, and helped pave the way for bigger solar telescopes.
