yes, messes up OSC a bit, but its a problem for broadband lum as well at lower angles.
A couple of us used dispersion correctors for high resolution imaging of Jupiter last year - it stayed below 35 degrees down here and the differential dispersion was quite noticeable, particularly in the blue channel. regards Ray
