Suppose you have taken a photo with some stars in it, and you can't remember exactly what you were trying to point at at the time. For example, this one
Nifty! Although I thought that clouds were something you wanted to avoid in astrophotography... nope, Magellanic clouds, we're OK.
I saw something about astrophotography just the other day... ah yes, Scott Manley has a video on something called Registax that lets you take a series of photos and combine to get a good composite.
I wonder whether you could operate a spacecraft this way? If you're too cheap for a proper star-tracker but you have a camera and an Internet connection, maybe you could e-mail pictures to these guys and get your orientation.
(I'm thinking of a plot point in the pilot to Salvage One, in which the navigation of Elon Musk's Andy Griffith's homebuilt junkyard Moon lander depends on a bootleg connection from Mission Control (Andy's junkyard) to a NASA mainframe. In mid-flight, someone at NASA eventually notices and halts the job, forcing the protagonists to admit their misdeeds and plead with the government for more free computer time.)
