Belt modifying an NEQ-6 pro astrophotographic mount - Part 2

This is part 2 in the belt modification project, which I have split into seven parts.

We're in the disassembly phase, and I'll show you how I removed the declination axis and the two stepper motors. This gave me access to the declination worm gear housing, which is the part I have to modify. I actually do the modification in part 5, but there's more disassembly to do first.



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. (http://www.rowanastronomy.com/)
