1x2 minute exposure.

Orion EQ-1 Equatorial Mount
Orion EQ-1M Single Axis Electronic Drive

New the RA axis of the EQ-1 mount had nearly 3/16" play. To accurize the mount I crafted a 1/8" brass bushing (1/16" on both sides, leaving 1/32" on both sides) to take up the play. This with a full disassembly and heavy bearing grease re-assembly greatly increased the tracking accuracy.
