17 cool gadgets that tease the future

Stellina is a larger portable telescope that works with a smartphone and tablet app.

Instead of searching the night sky yourself, you can select which planet or constellation you'd like to view from the app. The telescope will automatically find it and send images back to your device.

The telescope includes light-pollution filtering to help city-dwellers see more stars. The 15-pound device can run for 10 hours with an external battery.

The telescope will be available starting in March in Europe. Cost: $2,500
