Thanks for the reply. The problem I appeared to have was that, unless I had a monitor connected to the RP, I was unable to see the system booted up in VNC viewer. I finally got things working after I enabled SSH by installing an empty SSH file in the root drive. Whether this was necessary, I don't know. In any event, I can now operate my telescope mount using the Kstars/EKOS/INDI running on the RP, controlling from my PC using or through an android phone or Nexus 7 tablet--all using VNC Viewer.
Can you explain a little better the steps " Using autostart with Web Manager starts just INDI server and drivers selected in a profile. "? I don't know what you mean by "Web Manager"
I'm still struggling to get guiding working. I'll save that for another post.
