New - 12mm Kellner wireless illuminated reticule eyepiece. Ideal for high powered PEC and drive motor training (Meade ETX, LX90, LX200 etc) and guiding for astro-photography. Top-quality and engineering.

The cross-hair is twin-parrallel lines, ultra-finely engraved onto glass and has a smooth helical focuser to keep the reticule pinsharp for all users (see lower photo shot through eyepiece - please note that the picture is not very good and does not do the reticule justice!).

The pure red LED illuminator has variable brightness control and is supplied with batteries.
