I solved the wind issue by purchasing a trampoline with a busted mat at a garage sale for $30.
Like one of these:

I removed the mat, and put the scope inside. The safety net provides enough shelter from the wind to cut it down to the point where it doesn't affect the scope any more, and the whole thing is very lightweight to move around the backyard, and a lot cheaper than other options
Pixinsight is worth the effort, once you get your head around it, it is incredibly powerful.
