Firstly, your file is saying that you can only see the sky at all between 100 and 170 degrees azimuth. That is very extreme. Are you certain that is correct?
An example using an Overhead Sky Chart would probably be easier to understand. The sky is more naturally depicted.
I'm not certain how to interpret the dashed lines that you have drawn on your chart. You can't see *above* them? That would be very unusual... and I'm not sure SkyTools can do that. The way it works is that you define a "horizon" above which you can see things. This is for obstructions like houses or trees. If you are trying to define a region below a given altitude in the sky all the way to the horizon, then that isn't going to work, at least not directly. Is your telescope under a roof?
