Toying with the idea of moving up from my 10.5X70 binoculars. These have been great for quick looks when the weather, and energy levels, do not necessitate pulling out the big guns for a longer viewing session. I have serious astigmatism so I do view with my eye glasses on. The 82 mm, most likely from Oberwerk, seem to be a good compromise as an increase in size and quality, and they would work on my existing Series 5000 head/tripod. But with that said, is it worth the extra money to move up to the 100 mm? and the increased size and weight that goes along with the increase?
I would appreciate any real-world experience, also any actual comparisons between these sizes. I would use them primarily for general night time scanning, looking for nice wide field exploration of the night skies. I would plan on getting the ED versions
