1.25" 5X Barlow Single Lens

1.25" 5x Barlow Lens with M42 Thread for Standard Telescope Eyepiece Astronomy

This 1.25" 5x barlow features a fully-multicoated achromatic design. This short barlow will work in diagonals or reflectors, has internal darkening and edge-blackened lenses, and is parfocal with most eyepieces. It features a clear aperture of 18mm. Suitable for high contrast, high power applications in any telescope.
This barlow features an integrated twist-lock adapter / clamping mechanism to securely center and hold your eyepiece. The inner compression ring is made of polypropylene and will not mar your eyepieces. Unscrewing the twist-lock ring exposes a standard male T-thread (M42x0.75) underneath which can be used to couple imaging devices with the barlow.
