The William Optics’ ZenithStar range consists of compact yet very high-quality apochromats which are ideally suited for use with a DSLR camera. With these, you can capture excellent wide-angle images of large star fields. Combined with an optional flattener, these provide a corrected image field with a diameter of 45 millimetres right up to the edges.
The lightweight and compact ZenithStar apochromat and a DSLR fit well on a photography mount, such as the Skywatcher Star Adventurer or the iOptron Star Tracker - a simple, lightweight astrophotography system.
The ZS81 is an F/6.9 FPL53 Doublet air-spaced APO with a CNC machined ultra-high precision lens cell, F/5.5 with a optional x0.8-Flattener.
It comes with a innovative Bahtinov Mask Cover!
Despite its 81mm objective, the scope is still very compact and solid. Many airlines will accept it as carry-on luggage! Perfect size for serious observations of deep sky objects and planets. Solar observations possible with proper additional equipment.
This beautiful scope is everything you always wanted in a refractor, starting from extreme sharpness for clear details, and APO color correction.
The William Optics Internal Focus Design (WIFD) is an innovative and revolutionary design that combines a precise (patented) internal focusing mechanism with the highest quality optics available, offering the ultimate apochromatic refractor for astrophotography. Designed from the ground up to handle even the largest, heaviest, cooled cameras, this optics is uncompromising in its quality. The focuser movement is integrated into the main tube, so no adjustments are visible from the outside.
The user can enjoy the benefits of a conventional focuser with two fine focus controls without having to worry about the limitations normally found with conventional rear-mounted focusers (vignetting). The integrated position indicator window on the focuser allows instant verification of the graduated numerical display.
The focus is compatible with ZWO's EAF.
