How is the brightness gain in fluoroscopy calculated? … WebMay 12, 2024 · The minimum magnification is D O ÷ 7 = 90 ÷ 7 = 13. Gee, it seems like for a telescope that's less than awesome, especially since my 10x50 binoculars just about match that in magnification. Well, then, let's look at the maximum eyepiece focal length for this scope. f e-max = 7 × f R = 7 × 13.9 = 97.3mm. Jumpin' Jehosephat!
