I have narrowed my scope choices down to a 60mm to 65mm objective for backpacking reasons. With this objective size does anyone use 45 to 60 power magnification while spotting animals in the mountains. I have found anything above 40 to 45 power is not used often due to atmospheric/weather conditions. My scope choices are a non-ED glass due to cost and I have heard the HD/ED glass has less color fringing and is more noticable at the higher magnifications. I have decided on Kowa or Zeiss. Doug @ Camerland has a great deal on the Zeiss. I have packed on sheep hunts my Swarovski CT-85 with 20x65 and never used any power over 40 due to size of that scope and the need for a superior tripod. I am very interested in you input to finalize my decision. Living here in the Midwest I do not get much of a chance to evaluate premier spotting scopes in the field.
