Refractor 185 mm

Availability: manufactured on request; Type: refractor

185 mm represents the ultimate portable size refractor and it's a step-up in aperture, when compared to its smaller brother the 160 mm.
Suitable for imaging, the 185mm F/6.8 paired with our Field Corrector will deliver a corrected image circle of 55 mm diameter, allowing use of big chip cameras for capturing wide field deep sky images.
Although having a 'short focal ratio' this instrument is highly recommended to astronomers who enjoy a pure visual experience of Moon, planets, double stars and deep-sky objects.
Oil-spaced lens design helps this big triplet objective lens to quickly reach ambient temperatures.

* 3.5" rack and pinion type focuser from Starlight Instruments;
* dew shield with rotate & lock feature;
* bino-viewer friendly design;
* portable big size refractor;
