Oh yes this is an awesome barlow! The best of the 2"-ers IMO. Internal baffling works really well for max contrast and optically it is just superb. Works amazingly well in fast scopes with less expensive widefield EPs also (ie does very good job of cleaning up abberrations). For the price you cannot go past it if you need a 2" barlow!
ps I don't know Jacquie and no he did not pay me!
