The spacing I have with my QHY163M is close but not perfect and I am curious as to whether I should be trying to get it exact.
There's a (thin) region where the field is flat and a region where you can get infinity focus. They overlap but they're not the same. But if you're getting good stars in the centre and corners at the same time I don't think there's any need to tweak further.
