Baader Planetarium Fluorite Flatfield Converter

Description

Baader Planetarium 4x - 8x - the worlds best Barlow lens.

For the first time in astronomical history, a fully multicoated astronomical Abarlow lens@ has been designed with multiple CaF2 Fluorite elements (real CaF2 - not common EDGlass!). The result is a stunning performer. This is not a simple barlow lens at all. The FFC optical design provides a flat field, covering a 90mm circle with apochromatic correction from 3x to 8x focal extension. This unique design works equally well on all optical systems - be it f 4.5 newtonians, f8 apochromatic refractors, or f10 Schmidt-Cassegrains.

Our trademarked Astro T-2 System 7 provides each and every adapter in order to use the CaF2 Flatfield-Converter in conjunction with a widest array of telescopes, SLR or Digital
cameras, eyepieces a. o. related equipment. A separate group of 6x6 Spacer tubes, Changers, T-Rings and 2" adapters is available to offer unequaled performance for medium format cameras or 2" eyepieces.
