Just an update on Guide dog. The reason why when choosing the telescope tab that the program crashes is that you have to down load the ASCOM drivers for the 20 odd scopes that guide dog supports. The link for the Ascom drivers can be found in the pre-requisites area on the web page.

Hope this all makes sense for any of you that are interested in using guidedog for your guiding needs.
