12" or 10"

[編集]

The descriptions tells that this is both a 12" (305mm) and a 10" (254mm) telescope:

English: 10" Newton telescope on dobson mount. Français : Télescope de Newton de 30,5 cm (10 pouces) de diamètre, monture Dobson.

We should put the right one or remove the diameter measure if unknown. — Preceding unsigned comment added by Giambrox (talk • contribs) 07:23, 21 July 2020 (UTC)[返信]
