Artesky 102ED f/7 APO Refractor

This new APO guarantees a chromatic correction at the highest levels thanks to a precise and maniacal construction and numerous controls, both in the production phase and in the 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 is able to achieve very high levels of chromatic correction thanks to the combination of two optical glasses, the first is an Ohara (Japan) FCD1-B element while the second is a Lanthanum element, this combination produces a product free from chromatic error, managing to achieve much better performance than a corresponding doublet refractor.
