My barn-door tracker, manual version (2013-09)
+ very simple and lightweight + polar sight + corrective cam (pictured in reversed, storage position) + 1 crank turn / mn + used a audio/music player to give 5s tops to help turn the crank regularly - too lightweight cam ball - ball handle gets into images - rubber band proved not durable
