All Meade ACF optics include over-sized primary mirrors.

The f/8 OTAs are available in 10", 12", 14" & 16" apertures. Includes dual-speed mechanical focuser, Losmandy-style mounting rail, and an internal Crayford-style focuser design for zero-image shift focusing. The 14" and 16" include a primary mirror lock to aid in long expsoure astrophotography. Wider fields of view and short exposure time when compared to f/10 optics.

The f/10 OTAs are available in 8", 10", 12", 14" & 16" apertures. Feature single speed mechanical focuser, Losmandy-style mounting rail, primary mirror lock, and higher focal length that yield increase magnification, ideal for planetary and deep-sky objects.
