Astromania 1.25" 4-Elements 5x TeleXtender Premium Barlow Lens - apochromatic Barlow lens giving an excellent image
Astromania Barlow lenses stand for high optical quality. The four-element design provides excellent colour correction and ensures pin-sharp, high-brilliance images of the night sky.

Easy To Use
Simply insert the 1.25" 4-Elements 5x TeleXtender Premium Barlow Lens into your telescope's focuser or diagonal, and then insert any 1.25" eyepiece into the barlow lens, gently securing it in place with the knurled set screw grips. Then, adjust the telescope's focus wheels to enjoy 5x magnification of the eyepiece used.

Advantage of 4-Elements 5x Barlow Lens
Think of the money you can save with this practical and affordable telescope eyepiece accessory! The four-element design provides excellent colour correction and ensures pin-sharp, high-brilliance images of the night sky!

• Ring clamp: yes
• Series: pro
• Number of lenses: 4

• Coating of optical system: multiple
• Type: barlow & erecting lenses
• Connection (to the telescope or eyepiece): 1.25''


Compression Ring To Protect Your Eyepieces Your eyepiece or camera is connected via a compression ring, providing optimal protection from possible damage.		High-quality Aluminium Housing The housing is machined from aluminium, precision machined, sturdy for a long term use.		Safety Groove Safety groove to stop lens falling out, Avoid unnecessary drops, it's more convenient to use.		Rubber Armoured Grip There is high-grip rubber armouring in the centre section. This high-quality workmanship ensures a long life.

• Increase The Magnification Of Your Eyepieces

Use this premium Barlow lens between your eyepiece and telescope. This will increase the magnification without noticeable loss of optical quality. In comparison, a poorly corrected achromatic lens would decrease the contrast.The Barlow lens can therefore also be used as an alternative to having an additional eyepiece. The advantage is that you still have the better eye relief of an eyepiece with a longer focal length, meaning you can always observe in comfort.

• Premium Apochromatic Barlow Lens

As optical quality here is critical, you should really use a high-quality Barlow lens. Without a Barlow lens planets appear tiny and virtually no detail can be seen. Only by inserting the Barlow lens can planetary images be made to appear a reasonable size. The better the correction of the lens, the better and sharper the image of the planet will appear.Achromatic lensis a compound lens made by combining lenses of different glasses with different focal powers so that the light emerging from the lens forms an image almost free from unwanted colors.
