Visually, you get a fully fledged deep-sky telescope with it: globular clusters resolve, nebulae show structure, and planets are tack sharp. These are tubes that serve two hobbies at once.<\/p>\n<h2>Why a PDS?<\/h2>\n<p>The PDS versions are the photo versions of the Explorer line: the focal point is further out so that a camera comes into focus in prime focus, the tube is internally blackened to prevent stray light, and the focuser is built for the weight of a camera. Visually, you don't lose anything: with the included.<\/p>\n<h2>This is how to get the most out of this telescope<\/h2>\n<ul>\n<li><strong>Collimatie is bij f\/4,7 een vast ritueel:<\/strong> check for each photoshoot.
