The camera meter will be very confused with a scene of moon and stars, so you need to go manual mode and take several pictures until you find the correct settings. The moon is fairly bright and do not requires a long exposure.

I think you are getting too much light, and that's why you get the reddish/orange tint, even if it's too little to see it, the camera will take it on a long exposure.
