Pleiades 68: Seven-element astrograph for full frame
The William Optics Pleiades 68 is a pure astrograph, built around a seven-element optical design with FPL-53 glass and integrated corrector. Stars remain sharp points even in the corners of a full-frame sensor, without a separate flattener. Compact and lightweight: the entry into the Pleiades line, perfect on a sturdy star tracker or lightweight equatorial mount.
