iOptron CEM26 Center-Balance GoTo EQ Mount with AccuAlign Polar Scope & LiteRoc Tripod

With a head design and precise synchronous belt transmission that improve tracking accuracy with reduced vibration, the iOptron CEM26 Center-Balance GoTo EQ Mount makes an ideal mount for your astronomy and astrophotography needs when using small to medium refractors, reflectors, or Cassegrain optical tubes. Its combination of a powerful computer hand controller, traditional polar alignment scope, and integrated Wi-Fi module will enable you to spend less time aligning your mount and more time enjoying the wonders of the universe. In addition to the mount head, you also get iOptron s LiteRoc tripod that provides the stability of a 2" tripod, but with lighter 1.75" diameter legs.

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
• 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

Motors and Gears

• Synchronous belt transmission improves tracking accuracy, with reduced vibration, especially with heavy loads
• Less than ± 10 arcsec periodic tracking error
• 1.8° stepper motor with 128x microdivision
• 88mm, 144-tooth right ascension (RA) and declination (dec) worm wheels with zero backlash
• 55mm RA and declination ball bearings provide smooth movement with minimal vibration
• 35mm steel RA and dec axis shafts
• RA and declination gear switches release the gears for balancing OTA
• 0.17 arcsec (200 pulse/sec) motor resolution
• Low-power consumption: 0.5A (tracking), 0.8A (using GoTo)
• Runs on included 12 VDC 5A power adapter plugs into a standard 110-240 VAC North American outlet

Go2Nova 8409 Hand Controller

• 212,000-object database includes the moon, sun, planets, stars, comets, asteroids, and constellations
• Multiple assisted alignment procedures use the iPolar electronic polar finder
• Slew speeds: 1x, 2x, 8x, 16x, 64x, 128x, 256x, 512x, MAX (6° /sec)
• Permanent periodic error correction eliminates tracking errors for long-exposure astrophotography
• Automatic tracking rate based on the selected object being tracked
• ASCOM-compatible computer control with planetarium software via integrated ST-4 autoguiding port
• Serial port for firmware upgrade
• Adjustable key and display brightness
• 8-line/21-character LCD screen backlit 19-button user interface

AccuAlign Polar Scope

• Factory installed in the altitude axis of the mount
• Helps you quickly and accurately equatorially align your mount without an external device
• Two sets of three concentric circles are clearly marked for aligning the mount on Polaris in the northern hemisphere or Sigma Octantis in the southern

LiteRoc Tripod

• Innovative design provides the stability of a large 2" tripod, but with lighter 1.75" diameter legs
• Specially designed leg cuffs and sockets and locking levers add rigidity with less wobble when legs are fully extended
• Spreader locks legs into position to add stability and vibration suppression
• Set of three vibration-suppression foot pads help to virtually eliminate vibration caused by footsteps, passing cars & trucks, and wind
• Minimum height: 30" (76.5 cm)
• Maximum height: 46" (116.8 cm)
• Weight: 15 pounds
