You may already be familiar with PhotoPills app, but I just came across it and LOVE it. You download it onto your smart phone or tablet through the App Store and use it to plan photo shoots of the Milky Way, moon, or other celestial bodies based on a geographic location and calendar date. Do you want to know what day and time to take a photograph of the sun or the moon rising through an arch? PhotoPills will let you do that.
I think it could very well be a photographer's secret weapon.
