On Island of Bali (as in many places in tropical Asia) the bathrooms have openings to the sky to help vent moisture from showers. Early one morning I needed to use facilities but even with light on I could see clear sky through the opening. I turned off lights and grabbed my 6D and shot Orion. You can still see glow from florescent bulb and reflection on shower head. The red is from the timer I held. Not enough time to do sequence for stacking but a lucky shot none the less.
