CEM40EC Guiding Performance & Cable Management

I will test 3 things on my CEM40EC mount. First, cable management, let's check if it's reliable on both power and USB connection; Second, guiding, I will try longer exposure in PHD2 and see if it can help with my guiding, I will also run a guiding assistant in PHD2 to check the periodic error and backlash of my mount. And No. 3 will be a test of unguided exposures.
