iOptron CEM70 mount: center-balanced, powerful and precise (70 lb - 31.8 kg)

Visit iOptron CEM70 is a high-performance center-balanced equatorial (CEM) mount, capable of supporting up to 31.8 kg (70 lb)while weighing only 13.6 kg (30 lb). This charge ratio (~2.33) makes it particularly practical for both nomadic and stationary astrophotography.

Designed entirely in metal, it features a duo of 151 mm (248-tooth) gears, a very low periodic error (< ± 3.5 arcsec P-Peak) and permanent PE correction (PPEC) for ultra-precise tracking.

Its Go-To microprocessor (Go2Nova 8407/8410) includes a database of over 200,000 objects, 32-channel GPS and heated LCD screen. Polar alignment is performed via the integrated electronic iPolar.
