The Meade ACF 0.68x reducer with a 50 mm T-adapter is a professional set that allows you to extract the full potential of Meade's flagship astrograph models.
This reducer reduces the focal length by a factor of 0.68x, which allows you to effectively shorten the exposure time by half while increasing the telescope's field of view by up to twofold. The reducer is designed as a quadruplet with lenses covered with a full multi-layer coating. The reducer optics have been designed in such a way as to obtain full coverage of the APS-C matrix without vignetting. Together with the T-adapter included in the set, it is possible to adapt the reducer to a wide range of optical accessories, even those with a back focus distance of 105 mm.
Attention! The set is not suitable for visual observations. It is not compatible with older Meade optical tubes (without the ACF marking) and with standard SCT optical tubes. • focal reducer dedicated to Meade f/8 and f/10 ACF astrographs
