Omegon Pro 85/510 Apochromatic Refractor Triplet ED FCD-100

Omegon Pro 85/510 Apochromatic Refractor Triplet ED FCD-100: Japanese FCD-100 glass for a sharp price

The Omegon Pro APO AP 85/510 Brings a triplet with Japanese Hoya FCD-100 glass within reach of a serious but manageable budget. This glass has extremely low chromatic aberration: stars remain truly white, nebulae retain their natural hues, and contrast remains high, from the center of the image to the edge.

An apochromat converges all colors to a focal point. Stars remain white and point-like, without the purple edges of simple lenses: precisely what a camera sensor would mercilessly reveal.

Triplet on a light mount

With an 85 mm aperture and 510 mm focal length (f/6), this is a full-fledged deep-sky astrograph that can still fit on a mid-range mount. The 2.5-inch rack and pinion focuser with reduction supports a complete camera train without slipping.

Includes CNC tube rings, Vixen dovetail, finder adapter, and extendable dew shield: mount and get started.

Featured accessories

The Omegon Pro UHC 2-inch filter (€89) brings out emission nebulae under light-polluted skies. The Omegon Powerbank 10k 12V (€39.90) powers the mount and camera, and the Omegon Cronus 7mm eyepiece (€79) provides 73x magnification with high contrast.

For whom yes, for whom no

Good for: astrophotographers who want triplet quality without jumping to the top tier; this is the sharpest-priced 85mm triplet in the lineup. Not for: those who want the absolute maximum; the AP 85/560 with OHARA FPL-53 glass and case is the premium version. Undecided between the models? Choice assistant helpt.
