Some people say at the ground level 2”/pixel is the (almost) ideal ratio, so with your 0.86 you’re even better then the Nyquist criterion with regard to camera-telescope system ..
Yeah, I don't really subscribe to the 2"/pixel, I think 1-1.5"/pixel would be plenty wide enough to ensure sharp focus on 99% of nights
