It has an awesome mode where you hold the iPad up in the direction of the sky you’re interested in, and between compass, GPS and accelerometer it shows you the stars you’ll see in that direction.
Is this the program you're talking about?
Just wondering, as it sounds real cool ... :-)
Yeah, that’s it. Browsing this thread, I conflated it’s name with your handle. And yes it’s very cool; I can see a LOT of applications featuring such a “virtual window” interface.
That’s pretty cool.
