Test report for motor drive tracking

Due to weather and other business, I still have no time to mount telescope for any observation. Instead, I tried to install motor drive on the CQ3 EQ mount. I tested 30 sec exposure for Orion's belt. The result is pretty good. Upper is with motor drive and the lower is off. There is no trajectory for 30 sec. I guess it should be fine for 1 or 2 minutes. NEED to find other place to test to avoid light interference.

短時間的追踪效果還滿不錯的！等我搞清楚疊圖的藝術後，就可以進一步展現追踪攝影的威力了。
