Refractor 185mm


185 mm is the ultimate portable size refractor and a step-up in aperture compared to its smaller brother, the 160 mm.

For imaging use, the F/6.8 unit paired with our Field Corrector for Medium Format will correct an image circle of 55 mm diameter, allowing use of big chip cameras for capturing wide field deep sky images.

The longer version is addressed to those who want to enjoy visually the best images of Moon, planets and deep-sky objects. It shares the same platform/focal length, with our 200mm f8 refractor thus it should be considered mainly as an observatory instrument.
