So this is in reference to a astrotech 102 EDL I ordered, it’s 714mm fl f7, curious on if field curvature would be apparent on smaller chip cameras, I have a qhy462c which is tiny and a 485c which is 4 times bigger but still very small compared to a full size sensor.  Will curvature be an issue? Also should note, Mike did tell me a field corrector is in development for this scope.... nice to know in case I do upgrade to bigger sensors one day

It's really up to your preference. Try it and see. It is unlikely you'll see any issues on the 462, but you will probably start to see effects on your 485.

I have the SV102 Access with the same specs and the Williams Optics 6A III flattener/reducer works great with it.
