*The illumination device offers a continously adjustable illumination of reticle eyepieces like the Baader MicroGuide, but also of older ones. It also fits into a few finder scopes. The connector, the M8x0.75 thread, is common with crosshair eyepiecesl so they often can be fitted with this device. The electrical supply works wireless with two button cells SR41/SG3, so there is no risk to get tangled up.
