Frame SEO description iOptron CEM70 EC2<\/strong><\/h3>\n

The center-balanced equatorial mount iOptron CEM70 EC2<\/strong> is specially designed for demanding astrophotographers looking for the highest precision in long exposure imaging. Thanks to its dual system of high-resolution encoders on the right ascension and declination axes, it offers periodic real-time error correction on both axes, guaranteeing perfectly sharp images with no star trails. Its Center-Balanced Equatorial Mount architecture minimizes vibrations and optimizes stability, while retaining appreciable portability for transport in the field.<\/p>\n
