iOptron CEM70 mount: center-balanced, powerful and precise (70 lb - 31.8 kg)<\/h3>\n

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

Designed entirely in metal, it features a duo of 151 mm (248-tooth) gears, a very low periodic error (< \u00b1 3.5 arcsec P-Peak) and permanent PE correction (PPEC) for ultra-precise tracking.<\/p>\n

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.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

The version CEM70G<\/em> (or CEM70+Wi-Fi\/USB3) adds iGuider (on-board autoguider), a reinforced management cable, and USB 3\/Wi-Fi ports for direct PC control.<\/p>\n

Users confirm its reliability: \"tracking accuracy is amazing... 0.4\u2033 RMS\"<\/em> on a RC 1625 mm, and use with EdgeHD 11 + ZWO2600mc for long exposure astrophotography.<\/p>\n

Summary<\/strong>The CEM70 combines portability, remarkable capacity, Go-To precision, optimal tracking and integrated accessories (GPS, iPolar, iGuider in G version), making it a solid choice for the demanding astrophotographer.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"
