TI Series
Modified Harmer Wynne Astrograph
Main Technical features
The TI Series Astrographs is a “Cassegrain” type astrograph that uses aspheric primary mirror, spheric seconadary mirror and an high end three lens corrector. All the mechanical parts were been 3D designed and FEM optimized lefting material only where it needs to be to. This strategy in conjunction with a wide use of carbon fiber sandwich structural elements, allow to reach the best structural stiffness, thermal stability and lightness.

TI 35
TI35 Technical features
The TI 35 (350 mm of clear aperture) delivers a very compact, lightweight, high-performance astrograph in both super-fast f/3.5 (1230 mm focal length) and all-around f/5.0 (1750 mm focal length) configurations.
Measuring just 700 mm in length, 430 mm in overall diameter, and weighing less than 25 kg, the TI 35 is the highest-performing transportable astrograph available on the market.
