This is a refurbished unit and comes with accessories in the original box. Use the Sky-Watcher Evostar ED APO 72mm f/5.8 Guidescope to improve the precision of your autoguiding system, for wide-field astrophotography with small CCD imagers, or as an exceptional grab-and-go option for fast observation sessions.

The 72mm aperture is complemented by an extra low-dispersion (ED) element set in a doublet apochromatic lens design. These two optical features make the Evostar much more precise than standard refractors and guidescopes, producing crisp and clear high-resolution views with limited edge distortion and accurate color representation. To achieve the sharpest focus possible, Sky-Watcher utilizes a Crayford-style focuser. Unlike a conventional rack-and-pinion system, the focuser uses a toothless friction mechanism that smoothly moves the drawtube without the backlash that rack-and-pinion focusers suffer from. The focuser has a large 2-inch drawtube to accommodate full-frame imaging sensors without vignetting.

A mounting cradle-ring assembly clamps over the OTA and lets you adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and help with balancing, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any mount head with a Vixen-style saddle. To protect the optical tube and accessories during transport and storage, a hard aluminum carrying case is provided.

Uses include improving the precision of autoguiding systems by finely focusing the field and resolving guide stars better, capturing highly resolved wide-field images of the night sky using 2-inch or 1.25-inch imaging systems, and serving as a fast grab-and-go visual telescope for lunar and planetary observations.

The 72mm aperture is ideal for lunar and planetary use. The 420mm short focal length helps maintain a compact form factor and produces a fast f...
