I'm hoping someone out there can help me. Does anyone know what the thread specification (diameter and pitch) of the 2" nose piece of an Orion 2" manual filter wheel is? The 2" nose piece can be unscrewed from the main body of the filter wheel. I've heard that the threads are M41, but would like that confirmed, and I also need to know the pitch.
