Kelvin: Optics for smartphones. Focus on What Matters!

This digital project blurs the lines between the convenience of mobile photography and the power of professional optics.

The Levenhuk Kelvin MAK90 phototelescope is designed for anyone who wants to observe and photograph the night sky without the hassle. Simply assemble the telescope, attach your smartphone, and align the camera with the eyepiece. You can start capturing photos and videos right away and then share your inspiring photos with the world. The telescope does all the hard work of finding and tracking stars and planets for you.

Connect the telescope to your smartphone via Wi-Fi. The mobile app becomes your remote control and gives you access to over 11,000 celestial objects, from the Moon and Saturn to bright globular clusters and nebulae. Just tap a target on the screen, and then the telescope automatically finds and tracks it while you focus and capture images.

The Levenhuk Kelvin MAK lets you unlock the secrets of the universe and discover the beauty of the world around you. Use it to observe wildlife, examine the texture of bird feathers, explore rugged mountain terrain, study coastlines, or admire architectural details. The image through the telescope is correctly oriented, just like looking through a powerful spotting scope. To avoid accidental camera shake, use the included Bluetooth remote shutter for crisp, blur-free shots.

With its short tube, the telescope is easy to take along with you on country trips or travels, letting you explore space and take stunning photos anywhere and anytime!
