The Lumicon 2" Neutral Density 13 (ND13) filter, transmits 13% of all incident light, while blocking 87%.
The 1.25" filters employ industry-standard 1.125" x 42 tpi threads (except for Questar/Brandon, which use a thread pattern unique to Questar). The 48 mm filters employ industry-standard 48 x 0.75 mm threading, which thread into 2" eyepieces. All larger filters use the given size with 0.75 mm pitch (e.g. a 72 mm Minus Violet filter has 72 x 0.75 mm threads).
Note: Recommended for lunar observing with 8" (200mm) and larger telescopes
