{"product_id":"artesky-102ed-f-7-apo-rifrattore","title":"Artesky 102ED f\/7 APO Refractor","description":"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 factor F\/5.6 or use it at full focal length with the 1x variable flattener.

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

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
