I can barely see the jogged/traced output in the ACP window. I see "System.Dynamic" though. That is coming from TheSky. Object not set... from TheSky is usually a case of an older version of TheSky... it has a problem where letting an external program start it, it will throw that error (this is a guess). Start TheSky and connect to the scope first, then start ACP and go from there, connecting to the telescope etc.
