ARTESKY APO REFRACTOR 80MM DOUBLEET F/7.0

Artesky presents the new line of APO ED refractors, the new 80mm doublet with 2 element lens, the first is an FCD1-B Ohara (Japan) element while the second is a Lanthanum element

It is possible to reduce it with a factor of 0.8x and bring it to a focal length of 450mm with factor F/5.6 or use it at full focal length with the 1x variable flattener.

This new APO guarantees color correction at the highest levels thanks to a precise and obsessive construction and numerous controls, both during the production and sales phase; the image is not affected by any chromatic aberration and remains very clear and well contrasted.

APOCHROMATIC EXTRA-LOW DISPERSION

This apochromatic refractor manages to achieve very high levels of chromatic correction thanks to the combination of two optical glasses, the first is an FCD1-B Ohara (Japan) element while the second is a Lanthanum element, this combination produces a product free of chromatic error , managing to achieve much better results than a corresponding doublet refractor.
