Hi Ian,
Do not discount KStars/EKOS. The remote functionality and scheduling are great. Here is a link to the information page (below). It is free. Runs well off a Raspberry Pi at the scope. Remote control by laptop or PC from inside either by TeamViewer (free) or using Kstars for Windows remotely (which is my preference as the interface is nice and slick).
Lots of challenges but hey many here can help you out and who doesn't relish a challenge!

Lots of videos on line and your mount is ideal using indi-eqmod driver.
