Daca masori distanta dintre 12 spire (margini de filet), practic ai doar 11 pasi intre (n-1) ... adica exact pas de 1 mm. Poti compara si cu liniile liniarului daca se potrivesc la fix. (Apropo, si daca numeri liniile milimetrice pana la 1 cm vezi ca ai 11, nu 10  :wink: ) Verifica inca o data ce ai masurat, nu-ti bate capul cu standardele ca astea nu sunt filete standard.

@cmatei: Adaptorul ce l-am dat ca exemplu are si filet interior pentru filtre de 2"

Specifications:
Adaptation on the telescope side: M54x1 male thread / M48x0.75 (2" filter thread) female
Adaptation on the camera side: T2 (M42x0.75) male thread
Optical length: 2.2 mm
Mechanical length incl. threads: 12 mm
The M54x1 Thread is not the filterthread, it is the tread, many focuser uses as connection thread on their draw tubes.

Ideea e sa fie omul sigur ca are filet M54x1 (mm).
