William Optics Apochromatic refractor Pleiades 68 AP 68/260 Astrograph OTA

The William Optics Pleiades 68 mm APO is a flagship model tailored for professional astrophotography, representing the pinnacle of innovation in compact astrographs. Combining advanced optical design with top-tier construction, the Pleiades series sets a new standard for portable telescopes on the market.

At the core of the Pleiades 68 mm APO is its seven-element optical system, which features three low-dispersion super ED glass lenses. This sophisticated design ensures exceptional chromatic aberration correction, delivering sharp, high-contrast images with stunning detail. Its large aperture and high light-gathering capabilities significantly reduce exposure times, making it an ideal tool for astrophotographers looking to capture the finest celestial details.

The telescope is equipped with William Optics’ patented WIFD (William Optics Internal Focus Design) system, which provides precise internal focusing. This system maintains perfect alignment even when using heavy SLR or astronomical cameras, eliminating the risk of vignetting. The focuser is also fully compatible with the William Optics EAF (Electronic Automatic Focuser), further enhancing its versatility.

The telescope tube is mounted with precision CNC-machined clamps, complete with a socket for attaching a finder or guide scope, making it a reliable and flexible instrument for a variety of astrophotography setups.
