NightLight wrote in with a request for a red overlay to “use your iphone in the dark but keep your night vision.” I was reminded of the hacks about using red film in Astronomy Hacks: put it over your PDA or notebook computer, and you are all set. But to try it out, I needed to find an astronomy site that works well on the iPhone. Many online planetariums use Java to do their thing, but Your Sky is a great web site that does a couple of things simply and quite well: you can punch in your latitude and longitude, and you get a view of exactly what’s above you at the moment. You can tap to zoom in, and you can pan around. Just what I needed. (To save a little time, figure out your latitude and longitude on your Mac, save a bookmark for your Your Sky page in Safari, and sync your bookmarks to your iPhone so you can get to the star chart quickly.)

Another fun thing to do is create charts in XEphem or any other star chart software and sync them to your phone. It resizes them, so don’t expect excellent detail.
I create large, close-up images of things I’m trying to find, and it works pretty well.
