Hi all, Does anyone know where I can get a female-female threaded tube with the same thread as used to thread filters into EP's. The end of my bino OCA is male, as are my filters. I tried to cut the bottom tube off one of my old plossls that I got for free but wrecked the thread in the process. I took my bino to a dark site and taped (its the best I could do) the o111 lumicon to it to see what views are like.
Eta Carinae and tarantula were awesome. Really want to be able to screw a filter on.
