If you are connected to the internet now (broadband is best), you can watch a few of the introductory ACP videos. They will give you a great jump-start in understanding how ACP works, and what it can do for you. To see why we have focused on the web interface for routine use, see this video Acquiring a Color Series, and this one Introducing TheSky HD (iOS) with Built-in ACP Control:
You are about to integrate your telescope and CCD camera into a robotic observatory capable of acquiring images and updating its pointing as it does so, and offering these services via web pages. This is not a trivial system. I urge you to take it a step at a time, follow the suggestions, and work your way toward success in a careful and professional way. Trust me, if you try to take shortcuts, you'll end up frustrated and probably blaming the software or your computer for your problems.
Do not uninstall and reinstall if you encounter a problem! This is almost always a waste of time, and may obscure the real issue or worse, create new problems. Try to think out the problem, take a moment to actually read any error messages you see (they might be meaningful!), review the settings you made, and look for the obvious like an image that got clouded out or badly streaked.
Automated observing needs automatic focus. ACP uses either on the free FocusMax auto-focus software or the PlaneWave PWI auto-focus system for focusing. If you do not have FocusMax installed, go to the FocusMax web site and download the latest version, and at least check to see if you have the latest version. Do not use the FMAXUG FocusMax Yahoo! group except for discussion. If you are a PlaneWave owner, definitely use the PWI auto-focus which you can choose when setting up auto-focus in ACP.
Don't try to use ACP's auto-focus without successfully passing this test.
The PinPoint Astrometric Engine (included with ACP) requires either the Guide Star Catalog 1.1 or the USNO A2.0 catalog for star references. GSC is 350MB in size; A2.0 is over 6,000MB (6GB) in size. If your imager has a field of view smaller than 15 arc minutes, you'll need the A2.0 for best reliability. If you're unsure, install the GSC and try it. For details, see the support knowledge base article Downloading and Using Reference Catalogs. Please note that there is a lot of advice floating around on the net as to which catalogs are the "best". Virtually all of this advice is based on the needs of precision sub-arcsecond science astrometry. The GSC and A2.0 are the two best catalogs for general plate solving used to point a telescope. Really!
After installing the catalog of your choice, run the Catalog Checker program (included with ACP and accessible via the Start menu). Select your catalog type, click the button and then select the path to the root of your catalog. THe program will perform a short validation of the catalog files to see that they are all there and the right size.
