A Must Have Tool

I use Red Shift every day to see what is up in the sky, to learn more about astronomical objects, to plan viewing sessions, and to see gorgeous images. The red screen is essential for night time viewing (the only drawback is that the search text field is white even in dark-vision mode). I also have the Mac version for astronomy on cloudy nights!
