The new one has the added light baffle in front of the element to reduce ghosting or stay light issues that I suffered with on the older model. Get the new version if possible or you will have to baffle it yourself. On the link look at the enlarged photo and note the ring just in front of the glass. On the old model it is shiny black and about a 45° angle but on the new model it is now not shiny and it's 90°.<a href="http://www.agenaastro.com/GSO-2-2x-ED-Barlow-Lens-p/obar-gs-gs22b.htm" target="_blank">http://www.agenaastro.com/GSO-2-2x-ED-Barlow-Lens-p/obar-gs-gs22b.htm</a>Paul.</blockquote>
