Programs Compatible with NexStar, CGE, CGE Pro, CGEM
and AS-GT Scopes

Following is a list of programs that claim compatibility with various models of NexStar telescopes.  The only one I can personally attest to is my program, NexStar Observer List.  All costs are in US dollars and you should certainly visit the vendor's web site and study their latest information prior to purchase.  When known for certain, I have indicated compatibility with Vista - other programs may also work with Vista but I have not yet received confirmation.  If you know of any errors in the information below or of any additional programs, please email me at swanson.michael@usa.net.
