This Light-path Corrector works similarly to Barlow lenses but the main aim of its use is for example to reduce the optical path of a binoviewer (William Optics binoviewer) when focus cannot be achieved with the original factory setup.
E.g. the William Optics (WO) binoviewer has 105mm optical path, with the originally supplied 1.6x Barlow/Light-path Corrector this can be reduced to 47mm, but in many cases (many Newtonian reflectors) this will still be too long.
The 2.6x Barlow/Light-path Corrector will reduce it to 8mm thus  focus can be easily achived with any Newtonian reflector, but the image will suffer a bit.

We reckon that this 1.85x light Path-Corrector will reduce it to about 35-40mm.

The 1.6x version gives the best image, the 3x and 2.6x are a bit too strong, image quality suffers the most, so we believe the 1.85x is a good compromise. If you can use your Newtonian with a dSLR (i.e. focus can be achieved) then most likely you will be able to use your Newtonian with a binoviewer when used with this 1.85x Barlow/Light-path Corrector.

How it works: simply screw it in into the 28.5mm thread of the binoviewer at its lower end.

Please note that optically it's impossible to achieve the above without some vignetting.
