Caption: Figure 16.
View of the focal plane looking through a side porthole. Seven of 10 petals had been installed at the time of this photograph. One guider GFA camera is visible in the foreground, while three more cameras can be seen in the far background. The textured posts are light blockers covering stainless steel guide pins, used during petal insertion. The front central cap ring is also visible, structurally connecting and coaligning the 10 petals at their tips.
