ARTEC 200 Artesky: The new astrograph that will conquer you!

The design of a high performance astrograph was born in 2011, the idea was to create a tool that did not have collimation problems and that it had a solid mechanical made in Italy ... Our idea, our dream is finally become reality!

After numerous prototypes and tests, we are pleased to present the ARTEC 200 Artesky, a Newton 200mm F/4.0 native astrograph.

Our astrographs use the classic Newton native F/4.0 optical system consisting of a parabolic primary mirror in Pyrex certified with a minimum P/V 1/7 lambda accuracy, aluminised and treated with a reflection of over 97%, secondary mirrors have the same type of processing and treatment.

The carbon tubes are made with 3K twill thickness 2.5 mm finish, painted externally with semi-matt finish and dustproof.

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

All the mechanics are made of Aluminum Anticorodal with CNC machines or water cutting, for the realization of the secondary is used the technique of water cutting.

The 3" Artesky Solid Focuser features the "Rack & Pinion" system, which means a pinion and rack that allows a great load capacity (approx. 6kg) without any slippage.

The focuser is also equipped with 1:10 micrometric reduction; the flat base allows easy adaptation of the various commercially available motors (Moonlite, Lunatico, RoboFocus, etc.)

We designed the ARTEC line to serve a market of discerning astrophotographers who are especially concerned with ease and stability of collimation, optical quality and repeatability of results. To achieve all these goals, we soon realized that we couldn't look anymore at the telescope as at a standalone entity, but had to consider it for what it is: a part of an acquisition system which includes everything from the tube to the CCD. For example, in the design stage we paid special attention that no tilts are introduced by the draw tube of the focuser (we observed that several well-known focusers are simply unable to deliver according to their specs and to their price) and that the carbon tube shows no flexures under the cantilever load of heavier cameras. Also, when delivering complete instruments with correctors, we make sure that the mechanical adapter between the focuser and the corrector is custom machined on the outside diameter of each individual corrector, to prevent misalignments in the optical train. In our view, the main technical advantage of the carbon fiber (versus the thin metal used in some Far-East constructions) is more related to its thermal stability and overall rigidity than to just lighter weight.

This having said, there is clearly a technical cost to pay for all this extra rigidity and stability, and the weight of the ARTEC 200 is in turn higher than for other telescopes with the same aperture and optical design; it is still however fully manageable in the field, and well within the practical working range of very common and affordable mounts.

Technical features:

     Aperture 200mm
     Focal lenght 800mm
     Secondary diameter 88mm
     Diameter tube (external) 244mm
     Diameter tube (internal) 234mm
     Length of tube 720mm
     Weight 12 kg
     3 "Artesky Focuser with support for Newton

Included accessories:

     Carrying bag
     Anodized aluminum rings 6082 with retractable milling
     Losmandy dovetail
     Vixen dovetail
     Closure cap

Secondary mirror support

The secondary mirror holder, such as the rings and the primary mirror mount, is machined to full thanks to the water cut and then finely machined.

Detail of the 3" focuser and adapter flange

The focusing adapter flange is one of the most machined mechanical parts.

Working from the full, it is finely polished and then anodized with black.

3" Focuser - Back

The 3" Artesky Solid Focuser features the "Rack & Pinion" system, which means a pinion and rack that allows a great load capacity (approx. 6kg) without any slippage.

The focuser is also equipped with 1:10 micrometric reduction; the flat base allows easy adaptation of the various commercially available motors (Moonlite, Lunatico, RoboFocus, etc.)

Side view

In the side view of the instrument you can notice the milling of the retractable rings that together with the opaque coating of the carbon tube; the carbon weft is well visible and makes the instrument very elegant.
