Can someone tell me about how long my truss poles would be for my 12.5 f/6.4 would be? Would 44 inches be too short or would I be able to make those work? Having never built one, I have no idea. Thanks

You also subtract another 10-12" from the 56. This is half the diameter of secondary cage plus the ditance of a half racked out focuser. (I believe the is correct from memory). Even this is cutting it close to you 44". So take Dan's advise and get some longer tubes
