With an aperture of 111mm (4.37") the Astro-Tech AT111EDT ED triplet apochromatic refractor gathers over 18% more light than our 102mm (4") refractors. Contrast-enhancing knife-edge light baffles in the lens shade and the optical tube provide truly dark sky backgrounds and high terrestrial contrast. The edges of the lenses are blackened to reduce internal reflections and further improve image contrast. Extra-long focuser travel at 138mm (5.4") with large 2.7" diameter focuser drawtube helps keep the overall scope length as short as practicable for convenient travel and storage. The tube measures only 23.75" long with the lens shade retracted, and 28" long with it extended. The extra-long drawtube length also permits switching between visual or photographic use with no add-on extension tubes needed. The drawtube has a scale marked in 1mm increments so you can note individual focuser positions for easy return to the correct focus when switching between visual use and photography. A lock knob on top of the focuser lets you lock photographic focus. This is an amazing portable imaging or visual scope at an incredible price vs. quality ratio. Being F7 it's a true all purpose scope.
