Moon-filter (31,7 mm, 1 1/4”), not suitable for proteus
The moon filter protects your eyes from the sharp moonlight and increases the contrast at the same time. The filter is screwed in the eyepiece.
The moon-filter is an indespensable aid to observe the moon - a view without it is not recommended and can harm your eyes severly.
