Meade Advanced Coma Free Optics (ACF) Optical Design
The science behind the Meade f/8 optical tube starts with their patented ACF optics. Improving upon the original Schmidt Cassegrain design, Meade's ACF optics deliver the ultimate in clarity, contrast and flat field of view. Natural coma and optical abberations are eliminated allowing for pin point round stars to the edge of the field. These qualities make Meade ACF optical tubes excellent imaging instruments. However, by pairing this revolution in optical design with their Ultra High Transmission Coatings (UHTC), light transmission and detail are greatly increased allowing you visually discern fainter objects than ever before - an observer's dream! This OTA is built for speed too. Traditional Schmidt Cassegrains would typically have a field stop of f/10, at only f/8 your exposure times are exponentially decreased allowing you to get more imaging in each night.
