This special purpose eyepiece includes a reticle with phosphorescent-etched crossline patterns, internally illuminated so the lines are clearly visible against dark skies. Amongst the most advanced commercially available illuminated reticle eyepieces, this Series 4000 Plossl 9mm model includes micrometric x-y positioning controls which greatly facilitate locking onto the guide star. Turn the finely-threaded controls and place the reticle's crossline pattern precisely at the desired position in the field.
The sharp, high-power imaging of the 4-element multicoated Plossl optical system is complemented by a rubber eyecup that shuts out distracting stray light from the observer's eye. and a finely threaded helicoid-type dioptric adjustment.
