"Tracking performance in the RA axis is greatly assisted by a 180-tooth gear wheel, (compared to 130-tooth in the EQ3). This enables smoother, consistent results and accurate Go-To capability, making it easier to find and photograph your target, or to hold it steadily in view while observing."

Compatible with EQMOD using a Lynx Astro EQDIR adapter :-)
The Sky-Watcher EQM-35 Pro Synscan Modular Equatorial Mount offers the versatility of two mounts in one! A normal Go-To equatorial mount and a lightweight photo imaging mount.
The mount head looks similar to the EQ3 Pro but the EQM-35 Pro has much improved features and performance. For example the mount is equipped with a large 92.5 mm diameter RA worm wheel with 180 teeth for high precision tracking (compared to 130 teeth for the EQ3) and the strength of the rotary base has been increased. This results in greater stability, higher payload capacity and less vibration. The periodic error is also significantly improved.
In standard configuration mode with DEC and RA axes, you can use it as a normal Synscan™ equatorial mount with computerised Go-To and tracking in both axes with access to 42,900+ objects in the Synscan™ handset's database. The payload capacity for visual use is an impressive 10kg in this configuration.
For travelling you can remove the DEC Axis together with the heavy counterweight shaft and counterweights, reducing the instrument's weight considerably. In this configuration you can use a simple 45mm dovetail plate with tripod screw (not supplied) and fit your camera directly using a ball head (not supplied). Alternatively a DSLR can be mounted to a Sky-Watcher Star Adventurer L-Bracket (not supplied). With the DEC axis removed the mount only tracks in RA and you can easily take photos. Now the mount works in a similar way to the Star Adventurer mount, but heavier duty.
The EQM-35 Pro SynScan is a conveniently sized mount with impressive features suitable for both novice & experienced astronomers alike, for both visual and imaging use.
