Exactly. 3 weeks ago V4.3 was available for $75, i.e. until V5 was released, which had everything needed for PEC. May be they'll still sell it. I haven't asked.

Here's the V4 page (it's still works):

Prism's really big on the CCD side of things, along with scripting for automated asteroid and nova work, etc. Also the user group is French. There's an English group but it's pretty dead.

For visual observing Guide is definately the program to get. Too bad it doesn't do MEC with the LX-200 though.
