ZWO FF110-APO Astrograph with ZWO AM5N Mount, TC40 Tripod, and PE200 Extension Pier Set (ZWO). The set includes a ZWO FF110-APO apochromatic refractor with a 110 mm aperture, 766 mm focal length and f/7 focal ratio, plus a ZWO AM5N strain-wave mount, TC40 tripod and PE200 pier extension. The refractor has built-in field flattening and is designed for deep-sky imaging without a separate field flattener. With a suitable diagonal and eyepiece, it can also be used for visual observing. The mount provides automatic GoTo pointing and tracking; equatorial mode is used for long exposures, while alt-azimuth mode is intended for observing. The pier extension increases the clearance between the head and tripod legs, giving the telescope and accessories more room during movement.

The camera, power supply, guiding equipment and any ASIAIR controller are selected separately. An electronic focuser motor, focal reducer, diagonal, eyepieces, counterweight bar and counterweight are not included in this set. When selecting accessories, allow for their weight, optical-train length and clearance above the tripod. Long exposures require polar alignment of the mount and suitable tracking.
