Well, I didn't end up jinxing myself. Although I was worried about the weather and clouds, when we arrived at our campsite, the entire southern sky opened up. The iOptron Sky Tracker worked amazingly well. As a matter of fact, I didn't give it enough credit. I shot at ISO 1600, and I probably could have gone down to 800 without trailing.
I'm happy with my first wide-angle shot. Processing wide-angle shots is a lot different than deep sky, and I have a long way to go.
