Barlow šošovka DO-GSO ED 2x 2 palce

Double the magnification of any 2-inch eyepiece with this ED Barlow lens, engineered for edge-to-edge sharpness and true colour rendition. Its extra-low dispersion glass element effectively suppresses chromatic aberration, delivering high-contrast views ideal for lunar, planetary, and double-star observation.

Advantages

The fully multi-coated ED doublet provides high light transmission and contrast, while the anodized aluminium body with brass compression ring ensures a secure, non-marring grip on eyepieces. A built-in M48x0.75 filter thread accepts standard 2-inch filters, and the included dust caps protect the optics during storage.

Suitable for

• Visual observers using 2-inch eyepieces who want to double their magnification range
• Astrophotographers needing higher effective focal length for lunar and planetary imaging
