For imagers who want a lightweight apochromatic optical tube that excels for wide field astrophotography, the Sky-Watcher Evolux 82ED Doublet APO Refractor Optical Tube Assembly is the perfect match! While smaller and more lightweight than the popular Evostar refractors, it still has the same key optical qualities such as ED glass elements and Sky-Watcher flagship Metallic High-Transmission Coatings (MHTC) to remove chromatic aberration and false color to ensure images are crisp and clean without breaking the bank! The dew shield also helps remove stray light and condensation which can ruin exposures with too much sensor noise.

Included items consist of a foam lined aluminum case (19.5" x 10.75" x 7.75"), dual finderscope brackets, V-style dovetail, clamshell ring, adjustable dew shield and the optional reducer/corrector (477mm at f/5.8).
