1. ZEQ25GT Overview
Welcome to a new type of EQ mount! The iOptron “Z” design mount puts the payload weight at the center of
gravity allowing for greater natural stability. This also means the mount is extremely light compared to its
payload—a nice benefit when setting up at a remote site. Other features include an adjustable
counterweight bar to prevent obstruction with the tripod. And Polar aligning is quick and accessible all the
time since the Polar scope is not blocked by the DEC shaft.
The ZEQ25 is equipped with the most advanced GOTONOVA
®
GOTO technology, making it one of the
most powerful and accurate GOTO mounts available. It comes with over 59,000 objects in its database.
Plus, the Go2Nova
®
Hand Controller is intuitive to use with a large 4-line LCD screen to easily set up your
telescope and select where you want to go. The ZEQ25 – a new category of viewing and astrophotography.
Please read the instruction before operation the mount.
Features:
• A new design “balanced” equatorial mount for maximum payload and minimum mount weight
• Specialized astrophotography mount ideal for entry-level and intermediate Astro-photographers
• Payload of 27 lbs (12.3 kg) with the mount-only weight of 10.4 lbs (4.7 kg)
• Spring loaded gear system with customer adjustable loading force
• Gear switches on both R.A. and DEC axes for easy balancing when disengaged
• Adjustable counterweight shaft for 0º latitude operation
• Dual-axis servomotor with enhanced optical encoder for precise GOTO and accurate tracking
• iOptron AccuAligning

The Tension Adjusters are used as the last step to lock, and the first step to release the gears. When
disengaging the gear system, release the Tension Adjuster first. Then turn the Gear Switch to OPEN
position. When engaging the gear system, turn the Gear Switch to LOCK position first. Then tighten the
Tension Adjuster.
Never fully tighten the Tension Adjusters during operations. Fully screw in the Tension Adjuster and
then back out by about 2 turns. The optimum spot varies with actual conditions, but is mostly within 1-3
turns from the fully tightened position. Ideally, it should be at a position just deep enough to rid any free
movements (plays), while force on the worm assembly is kept at a minimum.
