- I happen to have this lens, so I used it. The lens f/4 is too fast for the Lhires III which is designed for f/10 telescope. When the the iris is closed down to 16 mm diameter (f/10) then the optics is a good match for the Lhires III f/10 design. When the iris is less than 16 mm diameter the spectrum resolution will decrease because the grating is not fully illuminated.
