I'm also going to ASTROCON 2017 and observing the eclipse from Casper - so I will finally get to meet the Astro-Physics team. I booked my hotel room more than a year in advance and I was still initially on a waiting list. This will definitely be a lot of fun.
This will be my first eclipse, so I'm just going to observe it. But, from giving a few presentations about the eclipse I've found some apps & programs that could be helpful to others. First is eclipsedroid, for android smartphones - it will give you an audible countdown for contact events. The non-free version can also be used to control camera shutters.
If you feel compelled to image it, then Eclipse Orchestrator is a good program to consider. There are a couple other programs to consider including one for the Mac, but I don't have the info with me here at work.
