Hi All
All other things being equal, what will help you see better, a mid-range scope (for example, and Opticron ES 80 GA with an HDF 20-60 eyepiece) with an 80mm objective lens, or a high-end scope (for example, a Swarovski ATX 20-60) with a 65mm objective lens?
Presumably the mid-range 80mm objective lens will theoretically let in more light, but will the higher quality optics in the high-end 65mm lens compensate for that? What is it that objective lens does but let in light (and increase weight)?
Advice welcome.
Thanks
