This is the introduction to the belt modification project, which I have split into seven parts.
In this part, I demonstrate the problem, and set out how I'll modify the mount to fix it.
In astrophotography, replacing a chain of gears with a single belt in an equatorial mount addresses the problem of backlash. After this modification, the only mechanical transmission left is the worm gear, and this is adjustable for backlash
Backlash in your astrophotography mount prevents an autoguider (such as PHD2) from making fast adjustments, especially in declination. This is because reversing the direction your mount is moving involves a delay when the gears take up the backlash. The more backlash, the slower your autoguider is to compensate when the guide star drifts, and the worse your tracking is.
The product I'm using is the Rowan Astronomy Belt Kit for EQ6 NEQ6 EQ6Pro NEQ6Pro and Orion Atlas EQ-G with Synscan goto drives. (www.rowanastronomy.com/)
