iEQ75-GT GoTo GEM

# 8700

The iEQ75-GT™ is a one-of-a-kind premium CNC-machined astro-imaging mount from iOptron. The iEQ75-GT™ offers the next generation GoTo technology from iOptron plus a tracking error of only 0.5 arc seconds realized by a Renishaw high resolution encoder-enabled double closed-loop tracking, driven by a precision DC servo motor. No other mount comes close to this! The iEQ75-GT™ has a payload of 75 lbs and includes a calibrated dark field illumination polar scope. Its unique base design makes it easy for just one person to carry to location.
