Explore Scientific ED APO 80mm f/6 FCD-1 Alu 2" R&P Fokussierer Refractor Achromatic Magnification 160 x (max)

The three-line design with Hoya FCD01-ED special glass and two air gaps enables a correction, which is clearly above the level of the two-line ED-apos, which are otherwise available in this price class.

A calculated polystirene dust of more than 0.9 speaks a very clear language here compared to the 0.8x possible with two lenses. This superior imaging performance combined with a solid mechanics results in a package that leaves nothing to be desired. In addition, an image field debner is available as an optional accessory for photography - thus the device can also be used without restriction.

The tube length has been optimized so that accessories with critical focus position can also be used. In all ED apochromates, a triplet lens with air gap and Hoya" FCD-1 special glass provides excellent imaging performance in visual use and photography.
