Crosshair eyepiece - 12.5 mm focal length - four-element - illuminated
The basis of this crosshair is a Plössl eyepiece with 12.5 mm focal length. The good field sharpness and the pleasant view make this eyepiece a good and inexpensive solution.
Also with this reticle eyepiece, the illumination of the double filament is continuously adjustable. So you can take the brightness of the guide star well into account.



[[The Double Filament Cross}]The double filament allows you to position the guide star neatly in the center. You can hold the guide star accurately or achieve precise positioning of the calibration stars on GoTo instruments.




Practical tip from Teleskop-Service
When tracking, we always recommend positioning one axis of the crosshairs exactly parallel to the adjustment in right ascension and the other in declination.

You accomplish this by using the hand control box to move the stars back and forth in right ascension at medium speed. You twist the crosshairs in the holder until the stars run parallel to one of the two double filaments.

This allows you to see immediately during tracking whether the deviation is in right ascension or declination and you can correct accordingly quickly and correctly.

Funktioniert gut, Batterieverbrauch ist relativ hoch. Anmerkung: Zumindest das mir gelieferte Produkt benötigt LR1130 Knopfzellen und NICHT die im Text angegebenen LR44!

"Tut, was es soll. Die Batteriehalterung ist ein bisschen tricky. Aber ansonsten perfekt."

"Das 12 mm Okular mit dem beleuchtbaren Doppelfadenkreuz eignet sich hervorragend, um einen Leitstern im Zentrum zu fokussieren und zu verfolgen. Die Schärfe des Doppelfadenkreuzes lasst sich unabhängig von der Schärfe des Sternenhintergrunds einstellen."
