If I use this project to map an Earth type planet at 5 pc, then use another iteration of the project to map
such a planet at 20 pc, will the resolutions be the same or not?

What would be the implications if the answer were yes?

i.e. if resolution were independent of distance. Wouldn't that mean it would be the same rez at 100pc? or a million pc?

I doubt it, but I was hoping...just for these implications.

Could resolution be improved by going further along the focus line?
