This crosshair eyepiece offers a highly comfortable view and is ideal for construction of finder scopes, but can also be used for manual guiding of astro images.
APM Illuminator for reticle eyepiecesThese eyepieces have thin crosshairs which does not impair the view, but still can be seen against the (usually) slightly brightened sky.If the sky is really dark, it is difficult to see the reticle, so it has to be weakly illuminated. For this purpose, the illuminator was developed.Red light glares less in the night and can be dimmed, too. Power is supplied by button cells, eliminating a cable which can tangle.
