Handcrafted Custom Telescopes and Precision Optics

Ultra Lightweight Mobile Telescope - AR UL Gemini

REVOLUTIONARY DESIGN LIGHTWEIGHT MOUNT. EXCELLENT QUALITY OF THE OPTICAL SYSTEM GUARANTEED.

Our new telescope "Gemini" combines the advantages of classical Dobsonian mount, improved and lightweight with easy and convenient truss tubular structure. Specially designed for easy portability this mount design combines several detachable elements with minimum dimensions made from quality plywood and aluminum tubes. Unlike other models telescopes, this model requires little space in transport and storage. The telescope can be assembled and ready to use within a few minutes. Assembling is extremely simple and fast, because the elements are joined by special clamps, without requiring the use of tools. Bearing system in height and azimuth helps the telescope to move smoothly and gently in all directions. Open structure design allows fast tempering of optics with the environment and contribute to the absence of convective currents, so typical of structures with tube, which often degrade the image. High quality plywood of the mount from the Austrian company JAF, is the most suitable material for sharp temperature differences and successfully fighting any oscillations and vibrations from the environment.

The optical system of all our models is of excellent quality, far above the average of commercially available telescopes. The primary mirror is made extremely precise from borosilicate glass of the German company Schott and accompanied by a certificate from interferometric tests, which ensures its high quality. The indicator for quality Strehl is almost always more than 95%.

And last but not least, you will not get anywhere such high quality at such a bargain price. Because we do not sell a brand, we sell quality!
