Double glued lens set;The true FMC coating process ensures that each exposed air lens surface is fully broadband coated to ensure adequate transmission and image quality

The Edges of the lenses are blackened；The edge of the lens is coated with a matt ink；which can effectively suppress the stray light interference and reflection；and offer up bright sharp images；The large nut lock screw is convenient for quick insertion and locking

The value must have 2x barlow lens doubles the magnification of any 1.25 inch eyepiece;double the capacity of an existing set eyepieces at the cost of a single eyepiece

SVBONY barlow lens provide a high power magnification allow you look more closely and more detailed at the moon's surface and other planet

2X barlow lens adopts 2 element one group broadband green film multi coated optical glass; the housing is blackened to maximize image contrast; both that make image more crisp and sharp without additional chromatic aberration

Fashion appearance;Different from the black that is common in the market;The silvery look makes the product look more stylish;The overall appearance is beautiful and upscale

Brass compression ring design; A brass compression ring can protect your eyepiece from marring or scratching the barrel; Keeping your eyepiece in new looking

Lens edges is blackened; Black paint on the edge of the lens; Reduce scattering of stray light and maximize contrast

The value must have 5x barlow lens doubles the magnification of any 1.25 inch eyepiece;double the capacity of an existing set eyepieces at the cost of a single eyepiece

Quality aluminum stock and black anodized body

3 element 2 group lenses with multi coated optics design make image more crisp and sharp

1.25" 2x Barlow lens fully multi coated metal with M42x0.75 thread camera connect interface for telescope eyepieces

Barlow lens 2x double the capacity of an existing set eyepiece;give a big magnification boost to any 1.25" eyepiece it's used with

The housing is precision machined from aluminum stock and black anodized to a hard finish

Provides comfortable viewing;Using the 2x barlow lens with a longer focal length eyepiece lets you achieve the same high magnification view; but in most cases the eye lens will be much larger; helping to reduce eye strain and improve comfort
