I posted this in "Observational Astronomy" but it might be better(?) here:

I have Celestron's 25x100 binos.

I'm using the Virtual Moon Atlas by Legrand.

In the Information area there's a listing for Minimal Instrument.

Most of the features I can see easily have 50mm refractor as the Minimal Instrument though I'm training my eye (slowly) to see smaller features.

How can I compare the mm refractor ratings to my 25x100s?
