Product description iOptron improved their ZEQ25 mount to create the CEM25EC GoTo EQ Mount. It features a motorized equatorial mount, the Go2Nova 8408 computer hand controller, a 2" stainless steel adjustable tripod, the AccuAlign illuminated polar scope, and a hard carrying case for the mount. A unique center-balanced "Z" design puts the payload weight at the center of gravity for enhanced natural stability and greater weight-to-payload capacity ratio. Its built-in 32-channel GPS receiver transmits accurate location and day/date/time to the hand controller, so when you change your position, the telescope can be set up quickly with accurate information. For precise tracking, as required during long-exposure astrophotography or observation sessions, the CEM25EC has micro stepper motors with digital encoders to precisely track the mount's position plus the capability for you to program out the Periodic Error Correction (PEC) common to all worm gears. Even before the PEC has been compensated for, the mount has an impressive periodic error of less than 0.3 arcseconds. With a maximum payload capacity of up to 27 lb, this mount is ideal for most medium-to-large refractor, reflector, or catadioptric optical tube assemblies (OTAs) with Vixen-style dovetail plates and is still capable of handling imaging rigs.The dual-axis stepper motors are highly energy efficient and use much less power than the servo motors they replace on this upgraded mount. The motors are controlled by the Go2Nova 8408 hand controller. This system has an internal database of 59,000+ celestial objects, with 60 user-defined objects to program yourself, and its firmware is updatable 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 no matter whether you're viewing the fast-moving Moon or much slower deep-space subjects.A heavy-duty 2" adjustable-height stainless steel tripod, larger and heavier than the 1.5" standard tripod, provides a steadier and more robust observational platform. It features a metal accessory tray that locks the legs in place for added stability and spiked feet to put it on a sure footing on rough or loose ground. To safely store and carry the iEQ45, a hard aluminum carrying case is also provided. It features a sturdy piano hinge, with dual locks and lock holes for security. On the inside, custom-cut foam padding protects the mount. - "Z-Balanced" Equatorial Mount
