Astrograph ARTEC 200 Lite

ARTEC 200 Lite – A new fast and solid astrograph for everyone

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 and high standard levels.

The ARTEC project was born in 2011 from the intuition of Mr. Seveso and then it was developed more and more with the help of our engineer Mr. Simeone.

Our astrograph use the classic Newton native F/4.0 optical system consisting of a parabolic primary mirror in Pyrex (or other on request) 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 3.0mm, painted externally with a semi-matt and dustproof finish, completely made in Italy.

The tube has an anti-dusted varnish coating inside it, this work is done to eliminate any kind of internal refelction and allows to have an evenly roughened surface.

All the mechanics are made of Alluminium 6061 with CNC machines and some details are made through laser cutting.

For the focuser we studied a new kind of R&P 2.5 inch focuser to make the perfect match with our ARTEC 200 Lite

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 motor kit, including EAF V2 from ZWO, Moonlite system or others.

Mechanics

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 the 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.

Quality Optics

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 lenght, 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.

Every ARTEC astrograph is fully tested by us before being delivered to our customers, every OTA must follow our high standards and our final tests on the field, under a clear sky, to become your Astrograph.

Handcrafted in Italy

Our astrograph is completely produced and assembled in Italy.

We have designed and take care of every little detail on our ARTEC; every screws are made out of 316 stainless steel and they are turned to make them brilliant and shine when looking at them.

The painting of the carbon tube is carried out by an expert painter specialized in carbon processing.
