• The William Optics Pleiades 68 is a 7element refractor designed specifically for sharp wide field imaging, featuring a very fast focal ratio of f/3.8.
• The multiple elements in the optical design result in significant improvements in color quality, light transmission, and contrast, crucial for deep-sky imaging during long exposures.
• With a 45mm image circle, the Pleiades 68 supports full-frame imaging.
• The inclusion of 48mm and 54mm adapters expands compatibility with a variety of cameras, providing flexibility for different imaging setups.
• The Pleiades 68 incorporates William Optics' patented WIFD internal focusing system, eliminating obstructions commonly associated with external rear focusers. This internal focusing system not only offers a sleek appearance but also reduces the risk of vignetting, unwanted shifts, and jolts that can lead to misalignment of optical elements during the focusing process.

The William Optics Pleiades 68 is a 7 element refractor, which is exclusively tailored for sharp wide field imaging due to its very fast f/3.8 focal ratio! With this multitude of elements, optics are improved drastically improving color quality, light transmission and contrast, all of which are important for imaging deep sky in particular when doing long exposure where subtle variations of false color and loss of resolution can easily become apparent.

The William Optics Pleiades 68 supports up to full frame imaging with its 45mm image circle. By supporting full frame sensors and having a fast focal ratio, wide field imaging will be obtained in extraordinary detail and color with very slim risk of vignetting at the edge of the field of view due to the wide illumination of the sensor.

To maximize compatibility with cameras, the Pleiades 68 comes with 48mm and 54mm adapters.

A major favorable value to the Pleiades 68 is William Optics patented WIFD internal focusing system. This is preferred for imaging because there is no obstruction that is typically caused with rear focusers that are external. As a result, all the focusing takes place internally inside the optical tube which in addition to having a slicker appearance, also reduces vignetting risk and unwanted shifts and jolts which can cause misalignment of the elements.
