TI 55: THE BEST ASTROGRAPH FOR YOUR OBSERVATORY

The TI 55 Astrograph range include four models to match every needs of modern research. 

• TI 55 f/2,6 – 1445 mm of focal length for extremely fast optics. It is based on a direct PRIME focus parabolic primary mirror with a 6.5″ Wynne corrector with 82 mm of back-focus. It offers highest productivity per night, great advantage for super-nova search, surveys, asteroids, and other fields of modern astronomy.
• TI 55 f/3,5 – 1925 mm of focal length for very wide corrected field and very fast optics. A killer for astroimaging setup.
• TI 55 f/4,9 – 2700 mm of focal length suitable for general use while maintaining an excellent focal ratio that allows reduced exposure times with respect traditional RC and CDK system.
• TI 55 f/6,5 – 3575 mm of focal length for deeper sky objects when excellent seeing condition allows the maximum resolution

The TI 55 f/3,5 and f/4,9 are based on a Modified Harmer-Wynne optical configuration.

The TI 55 f/6,5 is based on a Corrected Cassegrain optical configuration

Each TI55 model use a special designed and FEM optimized lightweighted QUARTZ mirrors. Both primary and secondary mirror are made using fine Quartz material that perform near to zero CTE.

Our FEM optimized lightweighted mirrors allows for TI55 models a glass weight saving of about 16 kg. It brings high advantage both in terms of thermalization time and in terms of holding structure masses. All this lets less deformation on structures and on mirrors itself and less weight and moment of inertia on your mount.
