Kenko Sky Walker SW-50A Astronomical Telescope

No matter how good the cameras in our smartphones have become, there are limits to what they can do when it comes to the moon and the stars: celestial bodies are still too hard to take a good picture of unless you have a pro-level camera and telephoto lens. The Kenko Sky Walker SW-50A Astronomical Telescope is here to help with that, allowing your smartphone to extend its capabilities by several orders of magnitude so you can take pictures of everything a 360 mm lens can catch, and that includes the night sky.

Besides the zenith mirror that allows you to look at the sky, the Kenko Sky Walker SW-50A Astronomical Telescope also comes with an erecting prism that you can use for ground observation. Combined with its altazimuth mount that you can use for horizontal and vertical movement, you can follow birds in flight or wild animals in motion from a safe distance. The telescope comes with three eyepieces (4 mm, 12.5 mm, and 20 mm) that allow magnifications of 18x, 28.8x, or 90x respectively, plus a light (820 g / 1.8 lbs) aluminum tripod that allows you to set up your observation spot anywhere you want!
