Classical Dobson

dobson 400 600

TDCM 400-500-600

 

Specifically designed to be transported and installed easily, the Deep-Astro instruments ensure accuracy and high quality robustness, the materials used have been chosen for their rigidity and treatments that have been processed in order to ensure longer life and resistance to the carriage and use conditions.

Indeed, the main structure of steel, welded and protected against corrosion and the epoxy paint at cold colorize and protect them all.
The aluminum parts are cut by digital milling machine ensuring high precision assemblies, they receive an anodizing making them more resistant and allowing to provide various colors for very elegant finishes and original customizations.

The Classic range has been specially designed to perform astrophotography, its propulsion system is unique. Coupled with our equatorial platform this set averages the performance of a classic mount (see specifications).
