The ZenithStar 71 ED from William Optics is a super portable telescope with quality optics. The 71mm ED air-spaced doublet is made with Ohara glass from Japan, and is fully multi-coated with STM super high transmission coatings for high contrast, sharp views. The optics are mounted in a CNC machined precision lens cell to keep them perfectly aligned.
The CNC-machined aluminum optical tube assembly of the ZS71 comes fully baffled to prevent light bounce and a retractable dew shield to further increase contrast. The William Optics 2" rotatable rack and pinion focuser included with this scope allows for 1:10 course and fine focusing. Its mechanical strength makes for extremely smooth movements and no backlash. The focuser can be locked down and will not flex or slip, even with a heavy camera on the back, and the tension is adjustable so that you can set it to accommodate accessories of different weights. The draw tube with graduated scale has a travel length of 80mm.
