In late 2019 developer Gion Kunz finally provided Ascom telescope support in Stellarium version 0.19.3 onward thus eliminating the requirement to use StellariumScope in the future.StellariumScope can still be used but the developer recommends you adopt Ascom controlįor EQMOD users obviously the latest Ascom platform drivers must be installed as well as the EQASCOM driver and Stellarium version 0.19.3 From a Stellarium perspective when you press cntrl 1 it commands telescope 1 to Goto the selected object, cntrl 2 moves telescope 2 and cntrl 3 moves telescope 3 in the same way.Stellariumscope receives a notification when each of these moves are activated but for telescope 2 and telescope 3 it simply uses these notification events as triggers to initiate Ascom Stop and Sync functions.The telescope 3 Sync function has nothing to do with Stellarium at all, Stellarium doesn’t even know its happening it thinks it’s moving a telescope.Now this is where EQASCOM uses this telescope 3 function to add Sync points to its alignment model ( n - point alignment ) You can make as many sync points or alignment points as you like and EQASCOM will apply the most appropriate transformation to make pointing corrections.

StellariumScope was developed by Scott Pinkham of ByteArts in 2007 as a third party software to configure Stellarium, connect your mount and provide functionality with slew, stop and sync commands thereby providing Stellarium with Ascom support for the control of the telescope mount.Stellariumscope connects to Stellarium as 3 separate telescopes.

It’s been bugging me for months to find more detailed information so after researching over the past week on the web here’s my summary of procedures for using Ascom control for your Skywatcher and Orion telescope mount with EQMOD users of Stellarium version 0.19.3 and later ( without the use of StellariumScope )
