TS 50mm f/4 ED Mini Refractor Telescope

This little telescope inspires all esthetes with its image. Even at the highest magnifications, you get an absolutely perfect image of a star. It is also possible to observe the landscape and nature. The contrast and sharpness will inspire you. The mechanics of this compact refractor are also uncompromising and allow perfect work, regardless of whether an eyepiece is used for observation or a camera for tracking.

A strong yet compact guide scope

Simply plug the autoguider camera into the 1.25" receptacle or screw the camera into the T2 thread and focus. You won't have any trouble focusing. The Crayford focuser's wide 33mm adjustment range makes it possible. heavy tracking cameras are the focuser carries it well, without tilting or giving way.The reward is clean, pinpoint stars.Due to the very good star definition, optics with an aperture of up to approx. 10" can be tracked well.

Important: Since the telescope has rigid tube rings, the homing camera must have a larger sensor chip to achieve a large enough field of view to contain a suitable guide star. Alternatively, you can swap the tube rings for guide tube rings and use the telescope in conjunction with a crosshair eyepiece as a finderscope.

A great telescope for observing landscapes and animals.

Use the compact refractor as a spyglass on vacation. When working with straight view, the image is upside down. But with a diagonal star or Amici prism, the image is straightened out. You can use any 1.25" eyepiece and magnifications up to around 100x are no problem for very good optics. Watch mountaineers on the steep face or watch exciting pencil drawings of rare birds. Thanks to the plate multifunctional with the 3/8" Photo tripod thread can be attached to any standard photo tripod.

A small but surprisingly powerful astronomical telescope

You will be amazed at what a really good lens with a diameter of 50mm can show. The craters and mare on the moon are as visible as the spectacular rings of Saturn or the beautiful set of Galilean moons of Jupiter. But many objects, such as double stars, planetary nebulae, or star clusters, can also be seen beyond the solar system. With the NED25 wide-angle eyepiece, for example, the small refractor becomes a large wide-field telescope, with which you can see an incredible 7.5° field of view in the sky. With nebula filters, even faint nebulae, like the well-known North American Nebula, are within your reach. Thanks to the flexible rail, the refractor can be attached to a photo tripod, a small stand or even a photo tracker.
