iOptron CEM26EC Center-Balance GoTo EQ Mount with Tripod & Hard Case

With a head design and precise synchronous belt transmission that improve tracking accuracy with reduced vibration, the iOptron CEM26EC Center-Balance GoTo EQ Mount gets an electronics & encoder upgrade compared to the standard CEM26 mount s that brings periodic tracking error down to less than 0.3 arcsec with a Real-Time Periodic Error Correction (RPEC) system. These design features and upgrades makes this mount an ideal for your astronomy and astrophotography needs when using small to medium refractors, reflectors, or Cassegrain optical tubes. In addition to the mount head & computer hand controller, you also get a solid, yet stable, stainless steel tripod to support your gear and a hard carrying case for the mount head and accessories.

Mount

• Ideal for small to medium sized refractors, reflectors, and Cassegrain optical tubes
• German equatorial configuration provides smooth and accurate single axis celestial tracking for observation and astrophotography
• Center-balanced " Z" design places weight over the mount s center of gravity to provide greater stability, smoother movement, and quieter running while requiring less counterweight
• < ± 10 arcsec of periodic error that can be trained out over time with PEC function on hand controller
• 26-pound payload capacity, excluding included counterweight
• 0-60° latitude ± 6° azimuth adjustment range
• Conventional AccuAlign illuminated polar scope
• Integrated iPolar electronic polar finder works globally no Polaris (north) or Sigma Octantis (south) necessary no need to rotate the mount during alignment
• Built-in Wi-Fi module allows you to control the mount via smartphones running controller app
• 3.8" Vixen-style dovetail saddle
• Retractable counterweight bar prevents hitting the tripod or otherwise interfering with the mount s movement 10-pound counterweight included
• 1.5" stainless steel adjustable-height tripod with leg-spreader/accessory tray

Motors and Gears

• Real-Time Periodic Error Correction system with high-resolution encoders continuously and automatically identifies and corrects intrinsic tracking errors to constantly improve accuracy over time
• Less than ± 0.3 arcsec periodic tracking error
• Synchronous belt transmission improves tracking accuracy, with reduced vibration, especially with heavy loads
• 1.8° stepper motor with 128x microdivision
• 88mm, 144-tooth right ascension (RA) and declination (dec) worm wheels with zero backlash
