Nothing much would be gained at any distance from boosting the size of the smallest resolved details beyond 70x for someone like me with eyesight acuity of 20/15, which is about average. I could already see 12% smaller line pairs at 70x through the 92mm reference scope set up next to the Harpia.
Hi Henry
If by "Nothing much would be gained at any distance" you mean extra detail, I wasnt refering to extra detail. I understand that you are saying no extra detail would be gained.
What I was wondering was whether the detail resolved by the standard eyepiece at maximum magnification, would be visible at greater distances than with the standard eyepiece, if there was a magnification increase.
Forgive me if you feel you have answered this but from my side it is still not clear that you have. For example your reference to seeing smaller line pairs through the other scope doesn't seem connected to my question about additional distance.
