The Rowan Astronomy kit for Heq5 upgrades your mount reducing periodic errors and backlash.

This kit replaces the factory spur gear drive train with timing belts. The pulley modification reduces the spur gear errors that are typical and it therefore reduces tracking errors. The belts also make slewing much more quiet eliminating the 'grinding' noise that the standard spur gears produce. The pulley ratio is the same as the factory gears. This means the Synscan hand controller is unaffected by this upgrade. All Synscan functions will operate as before.

A must have if you're getting the HEQ5. My guiding improved from .8-.9 rms down to .5-.6

A bonus would be quietness of the mount. No more teeth grinding metal gear sounds

Thanks!

Rowan eq5 belt mod

Ordered the Rowan belt mod kit for my HEQ-5 Mount which arrived in two days.
The instructions are easy to follow and highly recommend the pinion extractor which made removing the existing cog a breeze.
Took my time to ensure good tension on the belt and made several small adjustments to the supplied wheels to make sure the tracking was smooth.
All up about a two hour start to finish job.
Tracking is now improved with reduced backlash and quieter operation.
For the price this simple modification was worth every cent.
5 star for Rowan and testar.👍
