Enter in the hardware tab and the Gemini.Net should be available in the roll down selection per below. The Properties button allows you to set what interface you are using to the Gemini.Net setting and I use the Ethernet setting. If you are using the ethernet connection then SharpCap does not have to be on the same PC that the Gemini.Net driver is on.
For Stellarium and others you may want to see if it supports ASCOM's Alpaca server so that you can also run the Stellarium on another system to the Gemini.Net driver. Alpaca is a newish server/client model for ASCOM that does not require .Net (i.e. install Alpaca Server on the PC with the Gemini.Net driver and as long as the Stellarium has the Alpaca client then it can communicate to the Server syste with Gemini.Net - see
