TI 65: THE PROFESSIONAL ASTROGRAPH


The TI 65 Astrograph range include four models to match every needs of modern research.

  • TI 65 f/2.6 WPF- 1690 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 65 f/3.5 – 2275 mm of focal length for very wide corrected field and very fast optics. A killer for astroimaging setup.
  • TI 65 f/4.7 – 3050 mm of focal length suitable for general use while maintaining an excellent focal ratio that allows reduced exposure times with respect RC and CDK system.
  • TI 65 f/6.2 – 4030 mm of focal length for deeper sky objects when excellent seeing condition allows the maximum resolution

The TI 65 f/3.5 and f/4.7 are based on a Modified Harmer-Wynne optical configuration.

The TI 65 f/6.2 is based on a Corrected Cassegrain optical configuration

Each TI65 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 TI65 models a glass weight saving of about 25 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.

TI 65 THE MOST IMPORTANT FEATURES:

  • Effective optical aperture: 650 mm – Awesome optical performances for each model
  • High-End Lightweight Borofloat Schott mirrors
  • Extreme lightness – it allow a OTA weight around 80 kg that permits a 100 kg class commercial mount to be used
  • Extreme stiffness and thermal stability (thanks to extensive use of carbon fiber and carbon fiber sandwich)
  • Easy collimation
  • Built in integrated secondary mirror (Wynne corrector for WPF model)  high precision electronic focuser (ASCOM Alpaca compatible)
  • Built in integrated TI110 mm electronic field rotator (ASCOM Alpaca compatible) – Not avaliable for TI65 WPF 2.6
  • Built in electronic control boards and proprietary software for a full WI-FI control of the telescope
  • Automated dust cover (ASCOM Alpaca compatible)
  • Extreme modern Italian design
