The iOptron CEM40 is a next-generation center-balanced equatorial mount that weighs just 15.8 pounds while supporting payloads up to 40 pounds, featuring iPolar electronic polar alignment, built-in 32-channel GPS, and Dual Saddle compatibility for Losmandy and Vixen dovetails. The innovative center-balanced design places the mount's balance point directly over the center of the tripod, resulting in better stability and improved weight capacity to mount weight ratio compared to traditional German equatorial designs. Controlled by the Go2Nova 8407+ hand controller with an 8-line backlit LCD and 359,000+ object database, the CEM40 features slew speeds up to 4.5 degrees per second and includes Permanent Periodic Error Correction (PPEC) for precise tracking during long-exposure astrophotography. The mount includes integrated cable management, ST-4 autoguider port, and optional WiFi control capability, making it an excellent choice for both visual observers and astrophotographers seeking a portable, high-capacity platform.
