In addition, all lens surfaces have been provided with a green multi-coating to reduce reflections.

Astrophotography with the Barlow lens: You can also use the Barlow lens for astrophotography. Especially for compact objects, sometimes more focal length is required in order for them to be seen at a reasonable size in the image. The big plus: There is also no shadowing apparent on small image format camera chips.

Larger diameter - more scope for your lenses: The 2" diameter also allows you to insert your 2" eyepieces into the Barlow, doubling their magnification. This saves the need to buy additional eyepieces. The large lens diameter also means you will notice no shadowing in the image.
