Artesky presents the new line of APO ED refractors, the new 102mm doublet with 2-element objective, the first is an Ohara (Japan) FCD1-B 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 570mm with a factor of F/5.6 or use it at full focal length with the 1x variable field flattener.

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.
