    Great for Centering but...

    The double cross reticle pattern is very useful for centering your scope during Star Alignment actions. But this eyepiece has a few issues, too... 1 The 40deg FOV is quite narrow, combined with the magnification of 12.5mm. This can be a challenge when moving from the wide field of a finderscope. 2 There is no eyecup, and the eyelens is nearly flush to the exterior. This means glare from any external sources must be shaded away with your hand - while also trying to use your hand-controller to center your scope. 3 Focusing the reticle is done by helical means of the eyelens element. As you twist this outward, it quickly begins to get rather loose and wiggly in its threads - and there is no stop before it comes lose in your hand. All that aside, once you have your target within the FOV, the illuminated thin-lined double-cross reticle makes it quite clear where to center your scope.
