Barlow Lens ED 2x 2"
Now with ED lenses!
This is the ED (Extra low Dispersion) version of our famed Moonfish® Barlow lens 2x 2". It is well made both in design and craftsmanship, and it is the ideal companion to the Moonfish® Wide Field eyepieces.
Both lenses are Fully Multi-Coated (FMC) for best-possible contrast and transmission.
This Moonfish® Barlow lens ED 2x 2" comes with a removable adapter with brass retaining ring that lets you use 1.25" eyepieces and accessories. In the same way, the 2" body also presents a brass retaining ring to not mark the 2" eyepieces.
The lenses have a diameter of 37mm, thus you can even use 2" wide angle eyepieces without vignetting.
How to use the Moonfish® Barlow lens:
2x: Just put the Barlow lens into you telescope's focuser, then put the eyepiece into the Barlow lens.
1.5x: Unscrew the lower, black anodized part of the Barlow lens (the part holding the lenses) and screw it into the eyepiece like a filter.
Without the lens elements you can use the 2" body as an extension tube for 2" and 1.25" eyepieces.
