"Mounted in the OTA on my 10"" truss dob."
Written by Wolfgang Rafelt

"Für Selbstbauer sehr zu empfehlen. Leider fand ich keine Zeichnung oder Daten mit Bemaßung, was die Planung des Einbaus sicher vereinfacht hätte. So musste ich auf gut Glück konstruieren. Der Filterhalter selbst ist super und ist leichtgängig. Bei Kälte wird er etwas schwergängiger, klemmt aber nicht."
