TS-Optics 20 mm Croshair Eyepiece 1.25" - 70° Erfle - focusable Reviews
1/1 Reviews
Wrote by Johannes K. on 01.08.2023
"Qualität gut, aber leider komme ich damit mit dem TS-Optics 60 mm Winkelsucher nicht in den Fokus. (Schon ca. 10km entfernte Hochspannungsmasten sind nicht im Fokus) Das 23mm Fadenkreuzokular funktioniert gut."
