Summary[edit]
| Description |
Single-arm, motorized barndoor tracker. Arm is twice the usual length for 1/4-inch drivescrew. Motor spins at 2 RPM, rather than 1 RPM. Goal is to reduce periodic error by doubling the size. This barndoor tracker has been retired, but the parts (other than the tripod and Wimberly gimbal mount) are still assembled. |
