iOptron CEM25EC Equatorial GoTo Mount (1.75" LiteRoc Tripod, Hard Case)

BH #IO7103ECHC • MFR #7103EC-HC
iOptron CEM25EC Equatorial GoTo Mount (1.75" LiteRoc Tripod, Hard Case)
Key Features
  • Motorized Computer-Controlled EQ Mount
  • 128x Microdivision Stepper Motor
  • Go2Nova 8408 Computer Controller
  • 150,000+ Object Database
With improved tracking accuracy thanks to its extremely low periodic error of less than 0.3 arcsec, low power consumption stepper motor, and a lighter tripod, the iOptron CEM25EC Equatorial GoTo Mount is a specialized astrophotography mount for entry-level to intermediate photographers—especially if you're setting up in remote locations and need to carry your gear. Its innovative weight distribution design coupled with precise extended tracking capabilities creates a mount ideally suited for astrophotography or long-term observation. Its center-balanced "Z" design puts the payload directly over the mount's center of gravity, which gives it better stability and a greater payload capacity versus comparable EQ mounts. Additionally, the counterbalance shaft length is adjustable to keep it from interfering with the tripod over the course of the night. This version of the CEM25EC mount comes with a hard carrying case to protect it during transport and storage.

With improved tracking accuracy thanks to its extremely low periodic error of less than 0.3 arcsec, low power consumption stepper motor, and a lighter tripod, the iOptron CEM25EC Equatorial GoTo Mount is a specialized astrophotography mount for entry-level to intermediate photographers—especially if you're setting up in remote locations and need to carry your gear. Its innovative weight distribution design coupled with precise extended tracking capabilities creates a mount ideally suited for astrophotography or long-term observation. Its center-balanced "Z" design puts the payload directly over the mount's center of gravity, which gives it better stability and a greater payload capacity versus comparable EQ mounts. Additionally, the counterbalance shaft length is adjustable to keep it from interfering with the tripod over the course of the night. This version of the CEM25EC mount comes with a hard carrying case to protect it during transport and storage.

It includes the motorized mount, the Go2Nova 8408 computer hand controller, a 1.75" stainless tripod, and the AccuAlign illuminated polar scope. Its built-in 32-channel GPS receiver transmits accurate date, location, and time to the hand controller, so when you change your position, the telescope can be set up quickly with accurate information. Even with its highly accurate tracking capability and extremely low periodic error the CEM25EC has real-time periodic error correction so any errors can be immediately corrected so your long-exposure shots aren't ruined. Its maximum payload capacity of up to 27 pounds makes this mount ideal for most medium-to-large refractor, reflector, or catadioptric optical tube assemblies (OTAs) with Vixen-style dovetail plates, while still being able to handle imaging rigs and guide scopes. The included LiteRoc tripod has 1.75" upper and 1.5" lower leg sections, providing the stability and strength of iOptron's 2" field tripod but at a lower weight for easier carrying. Its leg cuffs, sockets, and lever locks are also improved to provide better rigidity and clamping, resulting in better overall performance.

The stepper motor and belt drive transmission is controlled by the Go2Nova hand controller. This system has an internal database of 150,000+ celestial objects, multiple alignment assistance procedures, and updatable firmware through the built-in serial port. With nine slew speeds and automatic tracking capabilities, finding and keeping objects centered in the field of view is easy whether you're viewing the fast-moving Moon or much slower deep-space subjects.

Mount

  • German equatorial design for smoother and more accurate tracking
  • Center-balanced "Z" design: Weight is placed over the center of gravity for greater stability, smoother movement, quieter running, and more efficient GoTo tracking to use less energy
  • 27-pound payload capacity, excluding included counterweight
  • 0-60° latitude; ±10° azimuth adjustment range
  • Built-in 32-channel GPS receiver for accurate day, date, time, and location information
  • Spring-loaded Vixen-style dovetail saddle
  • Adjustable polar alignment even during tracking
  • Retractable counterweight bar prevents obstruction by the tripod; 20mm diameter accepts any compatible weights
  • Includes 10.4-pound counterweight
  • Integrated bubble level
  • Works in the Northern and Southern Hemispheres
  • LiteRoc stainless steel tripod with 1.75" upper and 1.5" lower leg sections provides the stability of a 2" tripod but with a lower weight

Motors and Gears

  • High-precision digital encoder, stepper motor, and transmission reduces periodic error to under 0.3 arcsec for extremely precise long-duration tracking
  • Synchronous belt transmission improves tracking accuracy, with reduced vibration, especially with heavy loads
  • Low power consumption 1.8° stepper motor with 128x microdivisions
  • 88mm, 144-tooth aluminum right ascension (RA) and declination (dec) worm wheels
  • 55mm RA and declination ball bearings provide smooth movement with minimal vibration
  • 35mm steel RA and declination axis shafts
  • RA and declination gear switches release the gears for balancing OTA
