The astrograph MT SkyVision high performance structure is the latest instruments designed and developed within SkyVision workshops.

MT structure (Mobile Telescope) combines the best aircraft aluminum to carbon and stainless steel. It is light and efficient. It incorporates optics 250 to 400 mm in diameter for the opening ratios of between 3.6 and 3.3

Finishing MT telescopes is exemplary. The aluminum parts are processed by hard anodizing and completeness of hardware is stainless steel. This gives a very high level of finish and unfailing strength.

 


The astrograph MT are equipped as standard with a dovetail to Losmandy compatible format and can receive any type of eyepiece. A network of holes, on top of the structures, allows the mounting of accessories in parallel, such as a second instrument, or a guide window.


Particular attention was paid to the choice of carbon tubes. Rather than using tubes made from wound carbon cloth, SkyVision uses only pultruded tubes and hot-polymerized under pressure. This allows to obtain a composite wherein the proportion of binder is very small compared to the amount of carbon. The attachment system to the tubes ensures a stability of the whole structure and hence the optical alignment.

 


These tubes or fibers are in the direction of the length, crossed with a very small angle possible to get all the intrinsic qualities of carbon, in the length of the bar, ie in the sense of effort goes . Thus maximum stiffness, and the coefficient of almost zero thermal expansion.

 


The standard equipped secondary cage door eye Feather Touch “Starlight Instruments” is designed to carry heavy loads of “train CCD ” result.


We put all our experience and expertise to the realization of this instrument and as to each of our great care achievements was made to the structure supporting the optics. Collimation adjustment knobs characteristics of our brand are listed on our astrograph.
