Colossus Telescope

(The Colossus Telescope)
(concept for a 50-meter telescope using interferometry)

The Colossus Telescope (cited with The, i.e., "The Colossus Telescope") is a concept or a future telescope larger than the European Extremely Large Telescope. The concept features an effective primary mirror aperture of 50 meters using 60 individual 8m mirrors. (Being at the concept stage, somewhat different numbers have been cited.) It differs from segmented-mirror designs in that each 8m mirror would have a dedicated secondary mirror and optical interferometry would be used to produce the output, though each primary mirror would be off-axis, aiming light at a tightly-packed group of secondaries. Due to gaps between the individual mirrors, and an overall hexagonal shape, the collecting area would be about 70% of that of a single 50m mirror.
