Those with Skywatcher flex tube dob's will be fist pumping seeing this awesome documentary by NOVA which aired last night. Skywatcher Dob's played a key role in the incredible challenge that was the Ultima Thule mission, once again NOVA knocks it out of the park with this documentary. Watching just how incredibly hard it was to divert the new Horizons probe in flight to image this body at the extreme limits of our solar system is jaw dropping. This is an awe inspiring must watch!

From same video, near the end, you understand how uncertain they are of Thule's orbit just two days before approach.

I agree.  The video was outstanding, and seeing that Earth-based (relatively small) Dobsonian telescopes were the tools used to capture the most critically accurate location data was awesome!  I think fist pumping is a good analogy!  Does anyone know the story of how those Earth-based scopes were deployed and how the calculation was done?  What star was occulted?  Did the Dobs (they look like 12" Skywatchers) have goto, push, to, DSC, etc?  How was the star position established (I assume from Gaia)?  Incredible stuff!
