| \\ Assuming perfect optics, images at the fold mirror have coma 2 arcmin from on-axis (2.3mm from the center) that amounts to a 90% encircled energy radius of 14 microns, or 0.72 arcsec. This coma is linearly proportional to distance off-axis.\\ \\ | \\ Assuming perfect optics, images at the fold mirror have coma 2 arcmin from on-axis (2.3mm from the center) that amounts to a 90% encircled energy radius of 14 microns, or 0.72 arcsec.
