ARTEC 200 PRO - A revolutionary astrograph
The ARTEC astrograph series represents a new kind of instrument due to a strong and precise mechanical system with the use of high-end optics.
Our astrograph use the classic Newton native F/4.0 optical system consisting of a parabolic primary mirror in Pyrex aluminized and treated with a reflection of over 93%, secondary mirror has the same type of processing and treatment.
The carbon tubes are made with 3K twill with a thickness of 2.5mm, painted externally with a semi-matt and dustproof finish.
The tube has an anti-dusted varnish coating inside it, this work is done to eliminate any kind of internal reflection and allows to have an evenly roughened surface.
All the mechanics are made of Aluminum 6061 with CNC machines and some details are made through laser cutting.
For the focuser, we choose to use one of the most well knows instruments on the market: the Feather Touch FTF3015B-A.
This incredible and high-precision focuser features a rack and pinion system able to manage high loads capacity without any slippage.
The focuser is equipped with the standard 10:1 micrometric reduction and it can be equipped with any standard Feather Touch motor kit.
Thanks to the most advanced optical and mechanical design software used during the development, the ARTEC series offers a computer-optimized OTA to achieve uncompromising rigidity; all metal parts are CNC machined to guarantee optimal accuracy, ease of use, and stability of the collimation.
The ARTEC astrographs deliver stable focus over a wide range of temperatures thus limiting to the minimum they need for iterated refocusing operations - an important condition when using instruments with fast focal ratios during long imaging sessions.
All components are produced using only the finest materials available, such as special lightweight aluminum, stainless steel and bronze.
The sturdy spider of the secondary mirror support is made of laser-cut stainless steel.
The high resistance anodization is chosen for unbeatable resistance to all environmental conditions.
Finally, the generous extraction of the focal plane allows the use of the most challenging imaging trains, whether they are CCD, CMOS or the more popular digital cameras.
93%, correction equal to or better than λ/8 and Strehl > or = 0.95.
We recommend the coma corrector which we have tested and proved suitable to fit the optical design of our astrographs.
Some coma correctors can also reduce the focal length, so the system can reach the impressive focal ratio of F/2.8: as every experienced observer can testify, an outstanding mechanical construction is vital for proper collimation and reliable usage of such ultra-fast systems, an area where the ARTEC series sets the standards.
The correctors that we recommend provide a corrected field even at these very fast focal ratios.
Using the ARTEC 200 PRO at F/4.0 with Riccardi Coma Corrector guarantees you a 40mm perfect linear illuminated field; otherwise we test also this system with a full-frame CMOS camera without any problem.
