Thanks very much.

From what I understand the RV-6 varied alot in terms of focal length. My mirror has some writing on it which could either be a focal length variation so the tube cutter can know where to make cuts, or maybe the primary mirror's wave front error. Its hard to say. That said, I'm satisfied, I'm satisfied with its optical quality.

Thanks again,
