Why didn't I think of that! Actually the reason I ask is because I find that despite the corrector plate, the SN10 is not flat to the edge of the field with my QSI683 sensor and I'm therefore using a Paracorr. I haven't determined if this is causing other issues yet as I'm still trying to resolve other challenges like collimation, tilt, flexure and guiding.
