Gender changer. Allows you to convert a female 2" filter thread into a male 2" filter thread (note that a 2" filter thread specification is actually M48x0.75 and not 2"). Has a knurled grip in the center with a very short optical length of 1mm, and male 2" filter threads on either side. Made of black anodized aluminum. Maximum outside diameter = 50.6mm so this will slide into 2" focusers. Total length is 7mm (0.28").
