127mm f/9.4 OTA Construction - 127mm f/9.4 Optical Ray Trace (Focuser end)

...and a close-up look at the focuser end of the ray trace. Note that I did not add a scale model of the star diagonal to the ray trace. This is because I made initial measurements of how much of the optical train will be utilized by the diagonal. On the left side of the image and just below center is the tube length and back focus length. Also, please make note of how I adjusted the openings in the baffles to allow for a 1.2" inch desired field size at the focal plane, as compared to if I would have made the baffle openings for visual use; with the openings contouring the actual optical path.

As mentioned on the previous page, I can be contacted at the email address below if anyone has any questions, concerns, or need assistance.
