SVBONY 1.25" 31.7mm Barlow Lens 3x Apochromatic Three-element APO Design Plastic for Astronomical Telescope Eyepieces Astronomy Spotting Scope

The SVBONY 3x Barlow lens provides double magnification for the existing eyepieces to see more details of moon and bands of Jupiter clearly

Super easy to use;simply insert the eyepiece of choice into the Barlow lkens;then insert the barlow into the telescope

You could use the barlow lens with a low power eyepiece;so as a result;you will not only get a high power magnification;but also keep the exit hole on your eyepiece;keep a comfortable observation with wide view

Main Points:
3x magnification factor with 1.25" interface:
Double times magnify of any 1.25'' eyepiece

Barrel size:1.25"/31.7mm:
Fit for 1.25" telescope or eyepiece

With an air-spaced three-element APO design:
High quality observation without introducing additional chromatic aberration

Blackened lens edges and inner barrel:
To provide maximum contrast and sharpness

With safety undercut and brass compression ring:
The eyepiece barrels are not marred by the captive set screw

Light plastic material:
Weighs so light will not break the weight balance of telescopes

Please attention
Choose a right magnification for the telescope;if not;the image maybe not clear

Usually the maximum usable magnification is usually 2 times aperture in mm;if the objective lens is 90mm;then the maximum usable magnification is 225 times;so if go over 225;it is no use actually and make image not clear

When the barlow lens and eyepiece using together and the magnification is over the biggest magnification;the barlow lens observation effect appears nearly zero or imaging becomes blurred;in order to reduce the influence of imaging;careful selection of barlow at different magnification
