Sky-Watcher MD-EQ3 motor drive for EQ3 Mount

After endless months of messing with arduinos and stepper motors, I finally broke down and spent the hundred bucks on the MD-EQ3. I should have just done this at the start. A year ago, I could barely take an eight second exposure at 750mm, now I'm regularly taking four minute exposures at 1500mm, and can easily track Jupiter with a webcam at 3000mm for ten to twenty minutes. I highly recommend!
