indi_eqmod_telescope is not the device name, but the driver executable. You need to put "EQMod Mount", "GPhoto CCD" and "SX CCD LodeStar" respectively... but I think now that enough people got confused about this, I will change the whole approach for remote devices.
Ok, I reworked the remote devices selection, you can now select them as you would with local devices. The driver names in the Ekos options will be added the list to select from if needed. This will hopefully remove any confusion associated with remote drivers.
