APM Barlow lenses
Our totally new photo-visual apochromatic Barlow with real ED glass, calculated for the correction of Off-Axis Coma at Newtonian telescopes. This Barlow allows you to observe planets and deep sky objects at the edge from the 1.25" field of view with the same quality as on axis. Especially Dobsonian user will profit because most time the objects are not exactly centered on axis.
