Matthew -- assuming that BackyardEOS is not the problem, I might be able to help with this.
When you connect to the Moonlite ASCOM driver, you should see a Windows Form like the one I have attached to this post. For some reason it starts off minimized, so it will probably not be on the screen as such but rather down on the Windows task bar.
Here, you can set the focuser starting position. This is 0 by default; if you connect to the focuser with the draw tube extended halfway, the driver will not move the focuser in because it thinks there is no inward travel available, which would be the case if you were truly at 0 (fully racked in).
The solution is to either:
a) connect to the focuser with the draw tube fully racked in, in which case 0 is the correct starting point. You can also specify a maximum position of 30,000 if you want the full available range (for a 4.5" draw tube).
or
b) specify something like 15000 as your starting position in the ASCOM setup window and then connect to your focuser with the draw tube at your preferred starting position. This gives you 15,000 steps in either direction, which the BackyardEOS should honor if it's talking to the ASCOM driver correctly.
