I see 50 mm spotting scopes with 20-60 zooms and wonder if 50 mm is enough aperture to handle 60X. My wife uses a Nikon 10-22X 50 mm binocular and at 22X the image is still good but I can already feel it dimming.
I am now wondering if 60 mm can really handle 60X and deliver a reasonably good image.
I am shopping for a scope to handle 60X for long distance (1 KM or more) for bird identification and wondering if I need to go to an 80 mm to have enough light to support 60X.
What has been your experience?
