Newton Optical Tube Astrograph ARTESKY ARTEC 200E F/4.5
The ARTEC astrograph series represents a technological breakthrough in the world of astrophotography, thanks to its state-of-the-art production techniques and high-end optics.
The ARTEC project emerged in 2011 from an idea of Stefano Seveso, owner of Artesky, and was developed with the support of engineer Flavio Simeone. This series was designed for the most demanding astrophotographers, who are looking for a telescope that offers stable collimation, high-end optics and consistent image quality.
To achieve these goals, ARTEC was conceived not only as a stand-alone telescope, but as an integrated component in a complex imaging system. After more than a decade of development and design improvements, the ARTEC series continues to evolve through ongoing research into new technologies and engineering solutions.
Designed for the mobile astrophotographer
The ARTEC 200 is a 200 mm Newtonian astrograph, designed and manufactured entirely in Italy with top quality materials. It is the ideal instrument to get started in the ARTEC world, offering exceptional stability, portability and ease of collimation.
This astrograph uses a classic Newtonian optical design with a native focal ratio of f/4.0, and incorporates a quartz parabolic primary mirror, aluminized and coated to provide a reflectivity of over 95%, with the same treatment applied to the secondary mirror.
Thanks to its compact size and lightweight structure, the ARTEC 200 is perfect for traveling astrophotographers in search of dark skies. Its mechanical precision ensures stable collimation, making it a reliable alternative to common refractors or Cassegrain systems.
High-quality optics
ARTEC astrographs employ optics that match the mechanical precision of the instrument. Key specifications:
Reflectivity greater than 95 %
Surface correction of λ/8 or better
Strehl Ratio of 0.95 or better
The ARTEC 200 incorporates a 1.14x coma corrector, which increases the focal length to 912 mm and provides an effective focal ratio of f/4.5, with an illumination field of 55 mm.
The conical quartz primary mirror ensures exceptional thermal behavior by minimizing mass and eliminating lateral shifts, thus optimizing focus stability during long sessions.
Advanced mechanics
The ARTEC series is designed with advanced optical and mechanical CAD software, ensuring extreme structural rigidity.
All metal components are made of 6061 aluminum, CNC machined and laser cut to ensure high precision, collimation reliability and ease of use.
Main mechanical advantages of the ARTEC 200:
Stable focusing in the face of temperature variations, reducing the need for repeated adjustments.
Laser-cut stainless steel secondary support for superior rigidity and alignment.
Specialized anodization for unmatched weather resistance.
A wide back focus ensures compatibility with a wide range of accessories and remote imaging configurations.
The ARTEC 200 is equipped with the 3" PegasusAstro Prodigy electronic focuser, specially modified to withstand up to 9.5 kg of load without bending or twisting.
The included Rotation On-Axis (ROA) system allows precise manual rotation of the imaging train, ensuring perfect planarity. The system supports custom adapters and includes a standard M54x0.75 male thread.
ASIAIR compatibility
For users seeking a fully integrated experience, the ARTEC 200EZ version is available with full ASIAIR compatibility.
High-end carbon fiber structure
The ARTEC 200 tube is made of premium carbon fiber, selected not for its weight, but for its thermal stability and structural rigidity.
The carbon used comes from an Italian company specializing in composites for the automotive and aerospace industries. It is solid carbon fiber (not sandwich with foam core), autoclave-treated and with a matte exterior finish after final polishing.
The inside of the tube is treated with:
Dust repellent coating
Anti-reflective black matte surface
Rough finish to prevent condensation
