I need a native star-chart generator which takes Lat and Long and datetime and spits out a starchart.

AND I need an addition to settings that takes ALL visual output from the iphone and filters it to flat red where it would be white, down to black where its black and stays in the red spectrum all the way down. (For observing purposes.)

If there are any programmers willing to take it on, I'm willing to handle art for them.
