CEM40ec Performance with Heavy Payload
If you remember, last time I talked about some tracking issue with my CEM40ec under heavy payload. I reported the issue to iOptron, they took it very seriously. In 4 weeks, they sent me 3 beta versions of firmware upgrade, and the second upgrade fixed it. So before another new moon, I started imaging again.
