Re: What Do You Think About This?
It’s reasonable. J Gardavsky is an expert on the use of microscope eyepieces for astronomy. He made many posts on the old forum about this. It's a shame they are lost.

Re: What Do You Think About This?
Anyone who is serious about observing should have a set of good quality low count glass, whether orthos, plossls or microscope EPs. As OP indicated you can get them for pennies on the dollar and they will perform better than many entry level telescope EPs.
However, OP is also oversimplifying things. On axes sharpness is just one of the optical parameters, which is actually the easiest to get. What about field of view of the Nagler vs Nikon 0.96" microscopeEP ? Or 20mm eye relief of Radian?
Coatings on premium astronomy EPs are designed to suppress light scatter, improve contrast and light transmission for astronomical targets. From what I hear microscopy EPs which typically used in telescopes have simple coating. I doubt they perform to the same level on extra faint staff.
