Built for wide field astrophotography and observation, the Gear Series 115mm Triplet APO Refractor OTA from Starfield is fitted with an extra-low dispersion multicoated triplet lens for true colors and edge-to-edge clarity. The optical tube assembly's focuser is built to handle the weight of cameras, filter wheels, off-axis guiders, etc. with a CNC-machined brass rack and pinion mechanism. The focuser also supports 1.25" and 2" eyepieces for observation and comes with a camera angle adjuster for easy framing. The sturdy handle features a dovetail and holes for mounting accessories. The dew shield retracts for easier transport, and the whole OTA weighs just 15 pounds. Note that a mount and a tripod are required for use and do not come with the OTA.
